Question

2.(x+5)-3(2x-2)=52 ?

Answer 1

2*(x+5) - 3*(2x-2) = 52
2x + 10 - 6x - 6 = 52
2x - 6x +10 - 6 = 52
-4x +4 = 52 (:4)
-x + 1 = 13
-x = 13 - 1
-x = 12 (*-1)
x = -12

S = {x E R| x = -12}

Answer 2

$2(x+5)-3(2x-2)=52 \\ \\ 2x + 10 - 6x + 6 = 52 \\ \\ 2x - 6x = 52 - 10 - 6 \\ \\ -4x = 36 \\ \\ 4x = -36 \\ \\ x = -\frac{36}{4} \\ \\ x = -9$
