Simplifying
8x + 4 = 6x + - 10
Reorder the terms:
4 + 8x = 6x + - 10
Reorder the terms:
4 + 8x = - 10 + 6x
Solving
4 + 8x = - 10 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
4 + 8x + - 6x = - 10 + 6x + - 6x
Combine like terms: 8x + - 6x = 2x
4 + 2x = - 10 + 6x + - 6x
Combine like terms: 6x + - 6x = 0
4 + 2x = - 10 + 0
4 + 2x = - 10
Add '-4' to each side of the equation.
4 + - 4 + 2x = - 10 + - 4
Combine like terms: 4 + - 4 = 0
0 + 2x = - 10 + - 4
2x = - 10 + - 4
Combine like terms: - 10 + - 4 = - 14
2x = - 14
Divide each side by '2'.
x = - 7
Simplifying
x = - 7

8x+4 = 6x-10
To solve for x you'll want to move all the terms containing x onto the left side of the equation and all the other terms on the right side of the equation.
1. Subtract 6x from both sides.
2x+4 = - 10
2. Subtract 4 from both sides.
2x = - 14
3. Divide both sides by 2.
x = - 7
Answer is:
-7
