Question

1. 3(2x – 1) = 15
2. 6(x + 1) = 12
3. 2(4x + 3) = 22
solve for x

Answer 1

3(2x – 1) = 15
(2x – 1) = 5
2x=6
x=3

Answer 2

6(x + 1) = 12
x+1 = 2
x=1

Answer 3

Although Callisto's method is correct, I'd suggest practising using the distributive property, as it seems to be what the question is looking for.

Answer 4

2(4x + 3) = 22
4x+3 = 11
4x =8
x=2

Answer 5

Thanks guys

Answer 6

1. 3 (2 x - 1) = 15
2. 6 (x + 1) = 12
3. 2 (4 x + 3) = 22
