Reorder the terms:
4 + 2x = 3x + 4
Reorder the terms:
4 + 2x = 4 + 3x
Add '-4' to each side of the equation.
4 + -4 + 2x = 4 + -4 + 3x
Combine like terms: 4 + -4 = 0
0 + 2x = 4 + -4 + 3x
2x = 4 + -4 + 3x
Combine like terms: 4 + -4 = 0
2x = 0 + 3x
2x = 3x
Solving
2x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
2x + -3x = 3x + -3x
Combine like terms: 2x + -3x = -1x
-1x = 3x + -3x
Combine like terms: 3x + -3x = 0
-1x = 0
Divide each side by '-1'.
x = 0
