2x+5y=8

x-3y=-7

**Reiny**, Tuesday, April 13, 2010 at 3:13pmI will assume you don't want just multiples of the above, so we will need the actual solution to yours first

double the second:

2x - 6y = -14

subtract form the first

11y = 22

y = 2

then in the second:

x - 6 = -7

x = -1

now just make up any combination of x's and y's, sub in the 2 values and see what constant you get

e.g.

4x + 3y = -4 + 6 = 2

so 4x + 3y = 2 is one equation.

Now do the same thing for a second one
