hoblos · Answer

52 - 3x =9

hoblos · Answer

because he had initially $52
he bought 3 shirt of price (x) each and had $9 left

so the price of the 3 shirts + 9 must be equal to 52

3x+9=52
52-3x=9

anonymous · Answer

How do I solve 52 - 3x = 9?
I don't get it....

hoblos · Answer

52 - 3x = 9 
-3x = 9-52 = -43
x=43/3
