If y=5x-3 and 3x-y=-1, what is the value of y
Svet_ta [14]
Well if you make them both equal to y I got...
Y=-3x+1
Y=5x-3
But I don't think you can find it without the y since they are different variables. Like I know -3x and 5x are the slopes and 1 and -3 are the y intercepts but I'm stuck after that. Sorry if that wasn't any help.
Hope I helped.

6x+9/x-5 x is not equal to 5 find inverse
algol [13]
You have f(x)=(<span>6x+9)/(x-5) and want to find the inverse function?  Please note that the parentheses are obligatory here.

1.  Replace "f(x)" with y:   y = </span>(6x+9)/(x-5)
<span>
2.  Interchange the variables x and y:     x</span> = (6y+9)/(y-5)

3.  Solve this result for y:     x(y-5) = (6y+9), or xy-5x = 6y+9.  Then:
                                                             
                                            xy-6y = 9 + 5x, or y(x-6) = 9+5x
                                                             9+5x
                     Then                      y = --------------                       
                                                             x-6

Here x may not = 6, because division by zero would occur otherwise.

There need to be two number that add together to get 0

and two number that multiply together to get -9

3 + -3 = 0

3 · -3 = -9
