Question 898244
Graph all of the lines and look for the point(s) of intersection.
Example:
{{{y=x+2}}}
.
.
{{{graph(300,300,-5,5,-5,5,x+2)}}}
.
.
{{{y=2x}}}
.
.
{{{graph(300,300,-5,5,-5,5,x+2,2x)}}}
.
.
They intersect at (2,4). 
Verify with both equations.
{{{4=2+2}}}
{{{4=4}}}
True.
{{{4=2(2)}}}
{{{4=4}}}
.
.
.
Solution : (2,4)
