We have the equation:

4x - 3 = 2x + 5

Let's to change "-3" to the right side of equation, but changing the sinal

4x = 2x + 5 + 3

4x = 2x + 8

Now, we let's to change "2x" to the left side of equation. But, we also will go to change the sinal

4x - 2x = 8

2x = 8

We pass "2" dividing by the 8

x = 8 ÷ 2

x = 4

Tha answer to this questions is ,

X = 4

I hope this has helped.
