Question 27498
<pre> y = 4x + 11
3x - 2y = -7
<font face = "courier new" size = 4><b>
The first equation is already solved for y, so replace 
the y in the second equation by what y equals, namely,
(4x+11)

      3x - 2y = -7
3x - 2(4x+11) = -7
 3x - 8x - 22 = -7
     -5x - 22 = -7
          -5x = 15
            x = -3

Now to find y, replace x by -3 in the first equation:

   3x - 2y = -7
3(-3) - 2y = -7
   -9 - 2y = -7
       -2y = 2
         y = -1

So the solution is (x, y) = (-3, -1)
