**Damon**, Wednesday, February 19, 2014 at 1:22pmfirst no I get x = 5

5X = 3y - 2

3y = 3X + 12

----------------add

5 x + 3 y = 3 x + 3 y + 10

2 x = 10

x = 5

**Damon**, Wednesday, February 19, 2014 at 1:25pmy = 7x ^2 + 8x -6

we need to make sure solution is real and not repeated

look at b^2-4ac

64 + 168

positive so sqrt of + number,

you are right, two real zeros
