You can put this solution on YOUR website! y=f(x)
so if you isolate y you get the equation f(x)
3x+4y=15+6y
place the y variables to one side
3x=15+2y
remove the 15 from the y by subtraction
3x-15=2y
divide by 2 to isolate y
(3/2)x-(15/2)=y
so f(x)=(3/2)x-(15/2)
You can put this solution on YOUR website! Rewrite: so that y is a function of x.
This means that you must solve the equation for y, and, if required, replace the y with f(x).
Subtract 4y from both sides of the equation. Now subtract 15 from both sides. Finally, divide both sides by 2. which you can rewtite as: or in function form as:
