It's called "solve the equation for 'y' ".  That means move things
around so that you end up with 'y' all alone on one side, and
everything else on the other side.

You started with                        9x - 7y = -7

Subtract  9x  from each side:        - 7y = -9x - 7

Divide each side by  -7 :                  y = 9/7 x + 1

F(x) = -2x + 5<br> f ( ) = 13
scZoUnD [109]

Answer:

Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.

Step-by-step explanation:

so, if f (x) equals 13, you replace the x in the equation to 13.

f(x)=-2x+5

f(x)=-2(13)+5

f(x)=26+5

f(x)=31

I believe 41 would be your answer. Hope this is right and it helped!
