Simplifying
2x + 145 = 180
Reorder the terms:
145 + 2x = 180
Solving
145 + 2x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-145' to each side of the equation.
145 + -145 + 2x = 180 + -145
Combine like terms: 145 + -145 = 0
0 + 2x = 180 + -145
2x = 180 + -145
Combine like terms: 180 + -145 = 35
2x = 35
Divide each side by '2'.
x = 17.5
Simplifying
x = 17.5
