-3x + 4y = 11

Start by solving for y
-3x+4y=11
add 3x to both sides
4y=3x+11
divide both sides by 4
y=3/4x+2 3/4
now substitute f(x) in for y
f(x)=3/4x+2 3/4
I hope this helps

First add 3x to both sides so now you have 4y=11+3x. Then divide both sides by 4. Now your final equation as a function of x is y=11/4+3/4x.

-3x + 4y = 11
4y = 3x + 11
y = (3/4)x + (11/4)

-3x = 11 - 4y
3x = -(11 - 4y) = 4y - 11
x = (4y - 11)/3
there u go..
