Answer: x=0

<u>Combine like terms: 5x + 3x = 8x</u>

<u></u>8x = 7x<u></u>

<u></u>

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

<u>Add '-7x' to each side of the equation</u>

<u></u>8x + -7x = 7x + -7x<u></u>

<u></u>

<u>Combine like terms: 8x + -7x = 1x </u>

<u></u>1x = 7x + -7x<u></u>

<u></u>

<u>Combine like terms: 7x + -7x = 0 </u>

<u></u>1x = 0<u></u>

<u></u>

<u>Divide each side by '1'.</u>

<u></u>x = 0<u></u>
