The lesson's heading is the following: Solve each system of equation and the sum I need help with is:

5x + 2y = 12
6x - 4y = -7
Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++5%5Cx+%2B+2%5Cy+=+12%2C%0D%0A++++6%5Cx+%2B+-4%5Cy+=+-7+%29%0D%0A++We'll use substitution. After moving 2*y to the right, we get:
5%2Ax+=+12+-+2%2Ay, or x+=+12%2F5+-+2%2Ay%2F5. Substitute that
into another equation:
6%2A%2812%2F5+-+2%2Ay%2F5%29+%2B+-4%5Cy+=+-7 and simplify: So, we know that y=3.34375. Since x+=+12%2F5+-+2%2Ay%2F5, x=1.0625.

Answer: system%28+x=1.0625%2C+y=3.34375+%29.
