Answer:
Step-by-step explanation:First one is 2
2(6x+20) +2(8x-16)=180
12x+16x+40-32=180
28x+8=180
X=180-8/28=6
I think so my calculation may be wrong )
5x+2y = 20
For every hardcover book (x) you will be charged 5$.
For every paperback book (y) you will be charged 2$.
The amount of both types of books you buy has to be under or equal to 20$
For this problem you need to put the x values in for x in the equation. For example, put -10 in for x and calculate y, which is g(x)
