Answer:multiply by y
Step-by-step explanation:
Answer:
600
Step-by-step explanation:
To find 100% we can divide by 30 (to find 1%) then times by 100 (to find 100%)
90÷30=3
3×100=300
100%=300
200%=300×2
200%=600
3x+2y=22
3x-2y=2
we add these to equations together
6x=24
x=4
then we plug in x to find y
3*4+2y=22
12+2y=22
2y=10
y=5
solution is (4,5) (x=4 and y=5)
