Question

3 (x+3) -2 (x+3) =8 (x-3)

Answer 1

$3(x + 3) - 2(x + 3) = 8(x - 3) \\ 3x + 9 - 2x - 6 = 8x - 24 \\ x + 3 =8x - 24\\ x - 8x = - 24 - 3 \\ - 7x = - 27 \\ 7x = 27 \\ x = \frac{27}{7}$


S = {27/7}

Answer 2

3 (x+3) -2 (x+3) =8 (x-3)
3x+9-2x-6 = 8x-24
3x-2x-8x = -24-9+6
-7x = -27
7x = 27
x = 27/7
x = 3,8
