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'.

$x = 0$

Answer:

x=0

Step-by-step explanation:

This question is actually asking us to solve for x

5x+3x=7x

So let's solve

8x=7x

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
