New Learning Composite Mathematics SK Gupta Anubhuti Gangal Class 7 Linear Equations in One Variable Practice 6A Solution

Solve the following equations.

(1) (a) 2x + 7 = 11

(b) 8 + 5y = 23

(c) 4x – 9 = 7

(d) y/7 + 1 = 3

(e) 6 + t/4 = 9

(f) x/3 + 9 = 1

(2) (a) 2x + 1 = x + 7

(b) 5x + 12 = 3x + 20

(c) 3y = 8y – 15

(d) 6p – 18 = 5p – 7

(e) t + 10 = 20 – t

(f) 7z – 18 = 28 + 2z

(3) (a) 5x + 8 – 2x = 14

(b) 5(x – 7) = -10

(c) -7x – 11 + 3x = 5

(d) 6 = -2(7 – c)

(e) 5(1 – 2w) + 8w = 15

(f) 17 = 3(p – 5) + 8

(4) (a) 3x – 12 + 4x = 6x + 6

(b) 3(2x – 1) – 2x = -3

(c) 12 – 6x = 6(4 + 2x) + 6

(d) 6 + 2(3x – 6) = 3(x + 2)

(e) 4(2x – 6) + 3 (x – 3) = 0

(f) 3(2y – 4) + 3y = 5(y – 4)

Solution Number 1, 2, 3 and 4:

(5) 8 + 25m – 8) + 3(m + 2) = 12 + 4(2m – 1)

Solution Number 5:
