Exercise 11.2
Q1.
Solve the following equations and check the solution in each case:
Y = 7
(C)
(a) x + 11 = 21
(b) 3x – 15 = 2x + 1
12
(d) 4m + 32.4 = -7.6
(e) 2x + 5 = 35 – 4x
(1) 18 + 3p = 6 + 6p
3
(i) 3x - - = 6
(h) 5(2x + 3) = 4(x + 1) + 2
(g) 5x –9 = 3x + 7

(0) 15(x + 3) - 3(x + 9) + 5(x + 6) = 82
(q) [7(2 - y) - 5(y +12)] - 3y + 6 = 5
(p) 9-2(x - 5) = x + 10
(r) 2(x - 1) - 6x = 10 -2(x -- 4)
