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
The answer is b for this question
The second sentence, "I love vanilla ice cream, but my sister likes butter pecan," has the correct punctuation. In a compound sentence, the comma always goes before the coordinating conjunction (In your case, this conjunction was "but.").
