Answer: x=4
Step-by-step explanation:
Simplifying
(14x + -15) + 139 = 180
Reorder the terms:
(-15 + 14x) + 139 = 180
Remove parenthesis around (-15 + 14x)
-15 + 14x + 139 = 180
Reorder the terms:
-15 + 139 + 14x = 180
Combine like terms: -15 + 139 = 124
124 + 14x = 180
Solving
124 + 14x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-124' to each side of the equation.
124 + -124 + 14x = 180 + -124
Combine like terms: 124 + -124 = 0
0 + 14x = 180 + -124
14x = 180 + -124
Combine like terms: 180 + -124 = 56
14x = 56
Divide each side by '14'.
x = 4
Simplifying
x = 4
