**Mithra**, Saturday, July 23, 2011 at 5:57pm8x - 3y = 94 ---- Equation 1

2x + 22 = y ---- Equation 2

--------------

Sub y = 2x + 22 in equation 1

8x - 3(2x + 22) = 94

8x - 6x - 66 = 94

2x = 94 + 66

2x = 160

x = 160/2

x = 80

Now sub x = 8 in eq 1 or eq 2 and find for y

Substitute x = 80 in equation 1 or equation 2 and fine for y.
