10=3
5x+2y=3
5(5-2y) +2y=3
25-10y+2y=3
-8y=-22
Y=-22/-8
Y=2.75
6x+12y=30
6(5-2y)+12y=30
30-12y+12y=30
30=30

-2y=8-15
-2y=-7
Y= -7/-2
Y= 3.5
Answer:
10
Step-by-step explanation:
say x=0
then y would be 1
increasing x by 5 makes x=5
and then 5 x 2 + 1=11
so y went from 1-11(difference of 10) with the variation
so the answer is 10
