3x+3=4x+3+x
Add -2 and 5 to get 3.
3x+3=5x+3
Combine 4x and x to get 5x.
3x+3-5x=3
Subtract 5x from both sides.
-2x+3=3
Combine 3x and -5x to get -2x.
-2x=3-3
Subtract 3 from both sides.
-2x=0
Subtract 3 from 3 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -2 is not equal to 0, x must be equal to 0.
