Answer:
x=0

Combine like terms: 5x + 3x = 8x


8x = 7x

Solving for variable 'x'.

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

Add '-7x' to each side of the equation


8x + -7x = 7x + -7x

Combine like terms: 8x + -7x = 1x


1x = 7x + -7x

Combine like terms: 7x + -7x = 0


1x = 0

Divide each side by '1'.


x = 0

To make x the subject of formula substrate 7x from both sides

8x-7x=0

X=0

Therefore the final answer for x is zero
