#3**0 **

\(x=0\)

Let's see why:

\(5x+3x=4x\)

This is the original equation. First, let's simplify the left side and combine like terms:

\(5x+3x=4x\)

\(8x=4x\)

Subtract \(4x\) from both sides.

\(8x-4x=0\)

\(4x=0\)

\(x=0\)

You can also check that this answer is correct by substituting this value for x in the original equation and see if the equation becomes true:

\(5*0+3*0=4*0\)

\(0+0=0\)

Therefore, x=0 is the correct and only solution.
