Answer 1

$\huge\tt\colorbox{lightgreen}{Answer}$

$4(2x - 3) + 2(5x + 5) = 7(2x - 6) \\ 8x - 12 + 10x + 10 = 14x - 42 \\ 8x + 10x - 12 + 10 = 14x - 42 \\ 18x - 2 = 14x - 42 \\ 18x - 14x = - 42 + 2 \\ 4x = - 40 \\ x = \frac{ - 40}{4} \\ x = - 10$

Answer 2

$\huge\tt\colorbox{black}{\green{Answer}}$

$4(2x - 3) + 2(5x + 5) = 7(2x - 6)$

$8x - 12 + 10x + 10= 14x - 42$

$8x + 10x - 14x = - 42 + 12 - 10$

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:4x = -40$

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:x = \frac{ - 40}{ 4}$

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:x = -10$
