Answer:
x = -28
Step-by-step explanation:
(9x+42) - 5x = -70
add 5x to both sides
9x + 42 = -70 + 5x
subtract 42 from each side
9x = -112 + 5x
subtract 5x from each side
4x = -112
Divide each side by 4
x = -28
X= -28
(9x+42)-5x=-70
9x+-5x+-5x=-70
(9x+-5x)+(42)=-70
4x+42=-70
4x+42=-70
4x+42-42=-70-42
4x=-112
4x/4=-112/4
x=-28
(9x+42)-5x=-70
9x+-5x+-5x=-70
(9x+-5x)+(42)=-70
4x+42=-70
4x+42=-70
4x+42-42=-70-42
4x=-112
4x/4=-112/4
x=-28
