Answer:
Simplifying
70 = 2x + -10
Reorder the terms:
70 = -10 + 2x
Solving
70 = -10 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
70 + -2x = -10 + 2x + -2x
Combine like terms: 2x + -2x = 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 = -80
-2x = -80
Divide each side by '-2'.
x = 40
Simplifying
x = 40
