Question

3 (2×-3)+2 (×+1)=3×+18

Answer 1

a) 3*(2x-3)+2*(x+1)=3x+18
6x-9+2x+2=3x+18
8x-3x=18+7
5x=25
x=25/5
x=5

b) 2x-1/2=5x+1/3 
$\frac{12x-3=30x+2}{6}$
12x-3=30x+2
30x-12x=-3-2
18x=-5
x=-5/18

Answer 2

3(2x - 3) + 2(x + 1) =  3x + 18
6x - 9 + 2x + 2 = 3x + 18
6x + 2x - 3x = 18 + 9 - 2
5x = 25
x = 25/5

x = 5
