2y=4sqrt(x)

y=5

2y+3x=7

okay that was the question, and here's what i done:

i'm going to solve each equation for y now.

2y=4sqrt(x) --> [tex]y=\frac{4sqrt(x)}{2}[/tex]

2y+3x=7 --> [tex]y=\frac{7-3x}{2}[/tex]

i dont really know what to do with y=5 cause there are three functions if i graphed all three and i cant really find an example like this. What i think i must do is plugged in y=5 into the other functions and solving for x. which would give me the x-intercepts, which means i should integral in respect to x.

am i correct in thinking like this?
