7q+13 = 52 7q = 52-13 7q = 39 q = 39/7
-52 + 39 = -13
4 - (-39) = 4 + 39 = 43
If you do do 4 × 13 = 39 you will get it wrong. Working it out: 4 × 13 = 52 To get 39, you need to calculate: 3 × 13 = 39.
273
39 + 39 + 39 + 39 + 39 + 39 = 234
w + 13 = 39Subtract 13 from each side:w = 26
7q+13 = 52 7q = 52-13 7q = 39 q = 39/7
x=30...9+30=39 then divide by 3 equals 13.
39 ounces.

-h/3 -4 = 13 -h -12 = 39 -h = 39+12 -h = 51 h = -51
-39 minus -26 is -13
3*13=39

13/39 = x
-52 + 39 = -13
