Welcome to CBSE Worldz. In this video we will be discussing CBSE class 7 Maths Chapter 4 Simple Equations Exercise 4.1 full solved 1. Complete the last column of the table 2. Check whether the value given in the brackets is a solution to the given equation or not: (a) n + 5 = 19 (n = 1) (b) 7n + 5 = 19 (n = – 2) (c) 7n + 5 = 19 (n = 2) (d) 4p – 3 = 13 (p = 1) (e) 4p – 3 = 13 (p = – 4) (f) 4p – 3 = 13 (p = 0) 3. Solve the following equations by trial and error method: (i) 5p + 2 = 17 (ii) 3m – 14 = 4 4. Write equations for the following statements: (i) The sum of numbers x and 4 is 9. (ii) 2 subtracted from y is 8. (iii) Ten times a is 70. (iv) The number b divided by 5 gives 6. (v) Three-fourth of t is 15. (vi) Seven times m plus 7 gets you 77. (vii) One-fourth of a number x minus 4 gives 4. (viii) If you take away 6 from 6 times y, you get 60. (ix) If you add 3 to one-third of z, you get 30. 5. Write the following equations in statement forms: 6. Set up an equation in the following cases: (i) Irfan says that he has 7 marbles more than five times the marbles Parmit has. Irfan has 37 marbles. (Take m to be the number of Parmit’s marbles.) (ii) Laxmi’s father is 49 years old. He is 4 years older than three times Laxmi’s age. (Take Laxmi’s age to be y years.) (iii) The teacher tells the class that the highest marks obtained by a student in her class is twice the lowest marks plus 7. The highest score is 87. (Take the lowest score to be l.) (iv) In an isosceles triangle, the vertex angle is twice either base angle. (Let the base angle be b in degrees. Remember that the sum of angles of a triangle is 180 degrees). ------------------------------------------------------- Website: https://estudywala.com/ ------------------------------------------------------- follow us on facebook and do share with your friends   / cbse-worldz-105902717471973   Class 7 Maths chapterwise Playlist 👉Chapter 1 : Integers:    • Class 7 Maths Chapter-1 Integers   👉Chapter 2 Fractions and Decimals:    • Class 7 Maths Chapter-2 fractions and...   👉Chapter 3 Data Handling:    • Class 7 Maths Chapter-3 Data Handling   👉Chapter 4 Simple Equations:    • Class 7 Maths Chapter-4 Simple Equations   👉Chapter 5 Lines and Angles:    • Class 7 Maths Chapter-5 Lines and Angles   👉Chapter 6 The Triangle and its Properties:    • Class 7 Maths Chapter-6 The Triangle ...   👉Chapter 7 Congruence of Triangles:    • Class 7 Maths Chapter-7 Comparing Qua...   👉Chapter 8 Comparing Quantities:    • Плейлист   👉Chapter 9 Rational Numbers:    • Class 7 Maths Chapter-8 Rational Numbers   👉Chapter 10 Practical Geometry:    • Плейлист   👉Chapter 11 Perimeter and Area:    • Class 7 Maths Chapter-9 Perimeter and...   👉Chapter 12 Algebraic Expressions:    • Class 7 Maths Chapter-10 Algebraic Ex...   👉Chapter 13 Exponents and Powers:    • Class 7 Maths Chapter-11 Exponents an...   👉Chapter 14 Symmetry:    • Class 7 Maths Chapter-12 Symmetry   👉Chapter 15 Visualising Solid Shapes:    • Class 7 Maths Chapter-13 Visualising ...   To watch videos of other subjects, click the link given below: 👉Class 7 Science:    • Class 7 Science   👉Class 7 Maths: 🔔 Support me by donating 💰💳 Google Pay UPI ID usmanmohd3-1@okaxis class 7 maths exercise 4.1 solution class 7 maths exercise 4.1 question number 1 solution class 7 maths exercise 4.1 question number 2 solution class 7 maths exercise 4.1 question number 3 solution class 7 maths exercise 4.1 question number 4 solution class 7 maths exercise 4.1 question number 5 solution class 7 maths exercise 4.1 question number 6 solution #class7 #class7maths #simpleequations #cbseworldz
