X = 12y - 20
y = 12y
Y is obviously greater than 20 when you multiply it by 12, so that's a hint.
x = 42
y = 22
3.5 • 12 + 22 = 64
I hope this helped you!
No, 3,0 the x is to the right three and the y is zero. But 0,3 the x is zero and the y is up three
S + c = 79.10
s = 3.50 + 3c
3.50 + 3c + c = 79.10
3c + c = 79.10 - 3.50
4c = 75.60
c = 75.60/4
c = 18.90 <==== amount spent on coffee
s = 3.50 + 3(18.90)
s = 3.50 + 56.70
s = 60.20 <=== amount spent on soy lattes
