**Henry**, Tuesday, July 20, 2010 at 2:35pm1.8X + 6Y = 8

2. -9X + Y = 22

Using Eq. 2, solve for y.

Y = 9X + 22

Substitute 9X + 22 for y in Eq 1:

8X +6(9X + 22) = 8.

Solve for X:

8X + 54X + 132 = 8

X = -2.

In Eq. 2,substitute -2 for X and

solve for Y:

-9(-2) + Y = 22, Y = 4

Solution: X = -2, and Y = 4.
