Answer:
Simplifying
2x + 128 = 180
Reorder the terms:
128 + 2x = 180
Solving
128 + 2x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-128' to each side of the equation.
128 + -128 + 2x = 180 + -128
Combine like terms: 128 + -128 = 0
0 + 2x = 180 + -128
2x = 180 + -128
Combine like terms: 180 + -128 = 52
2x = 52
Divide each side by '2'.
x = 26
Simplifying
x = 26
