A Simplifying
3x + -16 = x
Reorder the terms:
-16 + 3x = x
Solving
-16 + 3x = x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
-16 + 3x + -1x = x + -1x
Combine like terms: 3x + -1x = 2x
-16 + 2x = x + -1x
Combine like terms: x + -1x = 0
-16 + 2x = 0
Add '16' to each side of the equation.
-16 + 16 + 2x = 0 + 16
Combine like terms: -16 + 16 = 0
0 + 2x = 0 + 16
2x = 0 + 16
Combine like terms: 0 + 16 = 16
2x = 16
Divide each side by '2'.
x = 8
Simplifying
x = 8
BSimplifying
4x + -2 = 2x + 2
Reorder the terms:
-2 + 4x = 2x + 2
Reorder the terms:
-2 + 4x = 2 + 2x
Solving
-2 + 4x = 2 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-2 + 4x + -2x = 2 + 2x + -2x
Combine like terms: 4x + -2x = 2x
-2 + 2x = 2 + 2x + -2x
Combine like terms: 2x + -2x = 0
-2 + 2x = 2 + 0
-2 + 2x = 2
Add '2' to each side of the equation.
-2 + 2 + 2x = 2 + 2
Combine like terms: -2 + 2 = 0
0 + 2x = 2 + 2
2x = 2 + 2
Combine like terms: 2 + 2 = 4
2x = 4
Divide each side by '2'.
x = 2
Simplifying
x = 2
