Answer:

y=9.25

Step-by-step explanation:

5x+2y=20

5(.3)+2y=20

1.5+2y=20

2y=20-1.5

2y=18.5

y=18.5/2

y=9.25

First substitute x for 0.3 and multiply by 5, and you get 1.5 Now we want to isolate the 2y so we subtract 1.5 on both sides. So we have a new equation of 2y=18.5 Now to isolate the y we divide 2 by both sides and you get y=9.25
