Answer:
x = 5
Step-by-step explanation:
Simplifying
2x + -2 + 5 = 13
Reorder the terms:
-2 + 5 + 2x = 13
Combine like terms: -2 + 5 = 3
3 + 2x = 13
Solving
3 + 2x = 13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2x = 13 + -3
Combine like terms: 3 + -3 = 0
0 + 2x = 13 + -3
2x = 13 + -3
Combine like terms: 13 + -3 = 10
2x = 10
Divide each side by '2'.
x = 5
Simplifying
x = 5
