Question

a) 3x (2 + 3) = 3 ( x + 36)

b) 3 x + 7 = 2 ( x + 4) + 1

c) 2 ( x+ 1 ) = 3 ( 2 x + 1) – 7 (x – 2)

d) 3. (x +2) + 5 = x + 12

e) x + 4.(x - 1) = 9 - 2.(x + 3)

f) x/2 = -5

g) 7.(x-1) = 2.(3x+1)

h) y - 8 + 5y = -3 +2y + 7

i) x/2 = 12/3

j) 4t + 9 = 3t + 5

k) 2x/3 + 1/2 = x/4 - 3/2

l) -10 + 4 - 2x = -4x - 7

m) 10x - 8 - 2 = 7x - 4

n) x/3 - 1 + 3/4 = x/2

o) a) x - 17 = -9

p) 2x = -7

q) 3x/2 + x/3 = 6

r) 49x/7 = 70

s) 5 + 7 + 2x = 17 – 3x

t) 4b + 9 b – 3 b = 65 - 25
