Answer:
3x + -7 = 5x + 12
Reorder the terms:
-7 + 3x = 5x + 12
Reorder the terms:
-7 + 3x = 12 + 5x
Solving
-7 + 3x = 12 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
-7 + 3x + -5x = 12 + 5x + -5x
Combine like terms: 3x + -5x = -2x
-7 + -2x = 12 + 5x + -5x
Combine like terms: 5x + -5x = 0
-7 + -2x = 12 + 0
-7 + -2x = 12
Add '7' to each side of the equation.
-7 + 7 + -2x = 12 + 7
Combine like terms: -7 + 7 = 0
0 + -2x = 12 + 7
