Answer:
61/100 61/1
Step-by-step explanation:
8x+6-9x= 2-x+4
8x+6+-9x=2+-x+4
(8x + -9x) + (6) = (-x) + (2+4) (combine like terms)
-x+6= -x+6
-x+6+x=-x+6+x
6-6=6-6
0=0
If 1 box weighs 7.5 pounds, then we find the weight for 15 boxes with this equation:
15*7.5
Multiply:
112.5
15 boxes weight 112.5 pounds
X=5. this is true because if y=0 and y=15-3x, then 15-3x=0. if x is 5, it would be 15-3(5)=0.
