Solve first equation for y:
5x+y=10
y=10-5x. Plug this equation into second equation
-x-(10-5x)=-2
-x-10+5x=-2
4x=8
x=2 (plug x into first equation)
5(2)+y=10
y=0
The answer is probably c if I’m correct
-3(-4y+3) +7y
Expand
12y-9+7y
Add like terms
19y-9
Answer:
$16
Step-by-step explanation:
90m+80m=1360
170m=1360
