Answer:
0
Explanation:
3x-3+x=4x-3
First you need to combine like terms on the left side of the equation
3x-3+x the like terms are 3x and x, remember there is always an invisible 1 next to x
add them:
3x+x=4x
so now we have
4x-3=4x-3
- we are subtracting 3 on both sides of the equation add 3 to cancel out the three
4x-3 4x-3
+3 +3
- The threes cancel out so we are left with
4x=4x
x=0
I hope this helps, I'm sorry if I'm wrong!
