Step-by-step explanation:
Shown Where? You didnt add a picture of a graph
Y=210-7X you have $210 and want to know how many books she can buy with that money.
Answer:
1 Factor out the common term 22.
2(2x+y)=102(2x+y)=10
2 Divide both sides by 22.
2x+y=\frac{10}{2}2x+y=
2
10
3 Simplify \frac{10}{2}
2
10
to 55.
2x+y=52x+y=5
4 Subtract yy from both sides.
2x=5-y2x=5−y
5 Divide both sides by 22.
x=\frac{5-y}{2}x=
2
5−y
