i knew they were both linear but i need to know where they cross

oh, find y.
i.e.xy=4
=>y=4x
=>y=4+x
substitute this in your other eqn. and solve for x

alternatively, make y the subject of both given equations and make them equal to each other.

Solve both equations simultaneously with some points. You will get your intersection point then.

2x2y=8
5y=5
y=1
x+1=4
x=3

start by doubling xy=4 and subtract equations

intersection points are y=1 and x=3 the the graph looks like this
