Answer:
Add '-3x' to each side of the equation.
-70 + 5x + -3x = -10 + 3x + -3x
Combine like terms: 5x + -3x = 2x
-70 + 2x = -10 + 3x + -3x
Combine like terms: 3x + -3x = 0
-70 + 2x = -10 + 0
-70 + 2x = -10
Add '70' to each side of the equation.
-70 + 70 + 2x = -10 + 70
Combine like terms: -70 + 70 = 0
0 + 2x = -10 + 70
2x = -10 + 70
Combine like terms: -10 + 70 = 60
2x = 60
Divide each side by '2'.
x = 30
Simplifying
x = 30
