What is the answer to 10x-3-x=52

Compare like terms first. 10x plus -x gives you 9x. So 9x-3=52. Than subtract 3 from both sides giving you 9x=49 . Next divide both side by 9, giving you X=5.4

10x-3-x=52
9x-3=52
+3 +3
9x=55
_ _
9 9
x=55/9

Add a 1 in front of the x, which gets you 1x. Subtract 1x from 10x and get 9x. You should get 9x-3=52. You then do inverse operation and add 3 to both sides. Cancel out the threes and add 3 to 52 which gives you 55. Bring down the 9x and divide both 9x and 55 by 9. You can't simplify this so you end up with x=55/9
Hope this helped
