2x+y=13
5x-2y=1

When asked to solve a linear equation the first step is to change the equation to slope-intercept form.

y=-2x+13
y=5/2x-1/2

Now you can graph the equation by hand or by claculator.
(Note: Calculator graphing is more accurate than graphing by hand.
  To find the point of intersection on a calculator hit 2nd, TRACE,5, ENTER,ENTER, ENTER.
x=3 y=7 When you get your point of intersection you now have the solution to your problem.

You sold us a cake with a hair on it.
