Answer: x=4
Step-by-step explanation:
How to solve x:
First you would collect like terms. Like terms are terms that have the same variable and powers. So, you would add x to both sides so it would be 3x-3=9 then you would add 3 to both sides so it would be 3x=12 then after that you would divide that by 3 which gives you x=4.
So x would be 4.
Side notes:
You do the inverse of what it tells you to “undo” the equation.
