5x+6y=18
5x=18-6y
x=(18-6y)/5
Use that in the other equation
18(18-6y)/5 - 15y = 36
64.8-21.6y - 15y = 36
28.8=36.6y
.7868=y
Now put that number in for y on the first equation
5x+6(.78) = 18
5x + 4.68 = 18
5x = 13.32
x = 2.66
and y = .78
It’s D
16/4 is 4 no more no less
Answer:
I = $ 1,937.50
Step-by-step explanation:
Steve did it perfectly, because he got the common denominator first, then expanded and subtracted.
-19/40.
This can be found using the slope formula.
