x + 6y = -4 3x - 4y = 10

**Damon**, Friday, May 30, 2008 at 2:48pmfrom the first equation:

x = -(6y+4)

substitute that for x in the second equation

-3(6y+4) -4y = 10

-18y -12 -4y = 10

-22 y = 22

y = -1

now go back and get x

x = -(6*-1 + 4)

x = - (-2)

x = 2

check

2 + 6*-1 = -4 sure enough

3*2 -4*-1 = 10 yes
