16+5x = 8x-5
Reorder the terms
16+5x = - 5+8x
Solving for variable for x
Move all terms containing x to the left, all other terms to the right.
Add - 8x to each side of the equation.
16 + - 3x = - 5 + 8x + - 8x
Combine like terms: 5x + - 8x=-3x
16+-3x = - 5 + 8x + - 8x
Combine like terms: 8x + - 8x = 0
16+-3x = - 5 + 0
16 + - 3x = - 5
Add - 16 to each side of the equation
16+-16 + - 3x = - 5 + 16
Combine like terms: 16 + - 16 = 0
0 + - 3x = - 5 + - 16
-3x = - 5 + - 16
combine like terms: - 5 + - 16 = - 21
-3x = - 21
Divide each side by - 3
x=7
