Simplifying
3x + -2 = 4x + -8
Reorder the terms:
-2 + 3x = 4x + -8
Reorder the terms:
-2 + 3x = -8 + 4x
Solving
-2 + 3x = -8 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-2 + 3x + -4x = -8 + 4x + -4x
Combine like terms: 3x + -4x = -1x
-2 + -1x = -8 + 4x + -4x
Combine like terms: 4x + -4x = 0
-2 + -1x = -8 + 0
-2 + -1x = -8
Add '2' to each side of the equation.
-2 + 2 + -1x = -8 + 2
Combine like terms: -2 + 2 = 0
0 + -1x = -8 + 2
-1x = -8 + 2
Combine like terms: -8 + 2 = -6
-1x = -6
Divide each side by '-1'.
x = 6
Simplifying
x = 6
