I think you mean "solve by graphing"
visit

I don't know how you can have trouble at the site. If you just enter
7/(4x4)
and
1/(4x+4)
into the first two function boxes, and click "Draw", you will see the graphs and where they intersect. That appears to be (3/4,1).
Algebraically, set them equal:
7/(4x4) = 1/(4x+4)
7(4x+4) = 1(4x4)
28x+28 = 4x+4
32x = 24
x = 3/4
so, y = 7/(7) = 1
