Answer:
C) 20, 4
Step-by-step explanation:
X = 5y
2x + 5y = 60
substitute in 5y for x: 2(5y) + 5y = 60
10y + 5y = 60
15y = 60
y = 4
x = 5y
x = 5(4) = 20
A
2x+5y=60
replace the x with 5y
2(5y)+5y=60
10y+5y=60
15y=60
divide both sides by 15
y=4
replace the y with 4
2x+5(4)=60
2x+20=60
subtract 20 from both sides
2x=40
divide both sides by 2
x=10
