3x - 3 = x + 5 subtract x from both sides 3x - 3 = x + 5 -x -x gives you.... 2x - 3 = 5 add 3 to both sides 2x - 3 = 5 +3 +3 gives you.... 2x = 8 divide both sides by 2 that gives you the final answer, which is....
x = 4!
let me know if you need help with anything else! :)
You can check this by replacing every X in the question with 4, then solve the problem normally. If the same number is on both sides of the equal sign, then it is correct.
