You can put this solution on YOUR website!
You can't solve it. This is an equation
with 2 variables, x and y.
The only way to solve it is if you assign
a value to either x or y. Then you can find
the other variable.
For example, if I say +x+=+11+, then
+y+=+4%2A11+-+2+
+y+=+44+-+2+
+y+=+42+
---------------
Another way is if you have 2 equations
+y+=+4x+-+2+ and
+y+=+-3x+%2B+7+
These intersect at 1 point, (x,y), and
the intersection is the solution
Here's the plot of these 2 lines:
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+4x+-+2%2C+-3x+%2B+7+%29+
