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:
