Answer:
Simplifying
5x + 10 = 6x + 8
Reorder the terms:
10 + 5x = 6x + 8
Reorder the terms:
10 + 5x = 8 + 6x
Solving
10 + 5x = 8 + 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.
10 + 5x + -6x = 8 + 6x + -6x
Combine like terms: 5x + -6x = -1x
10 + -1x = 8 + 6x + -6x
Combine like terms: 6x + -6x = 0
10 + -1x = 8 + 0
10 + -1x = 8
Add '-10' to each side of the equation.
10 + -10 + -1x = 8 + -10
Combine like terms: 10 + -10 = 0
0 + -1x = 8 + -10
-1x = 8 + -10
Combine like terms: 8 + -10 = -2
-1x = -2
Divide each side by '-1'.
x = 2
Simplifying
x = 2
