G=25+D
G+2=6(D+2)
G=(10+6D)
Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5CG+%2B+-1%5CD+=+25%2C%0D%0A++++1%5CG+%2B+-6%5CD+=+10+%29%0D%0A++We'll use substitution. After moving -1*D to the right, we get:
1%2AG+=+25+-+-1%2AD, or G+=+25%2F1+-+-1%2AD%2F1. Substitute that
into another equation:
1%2A%2825%2F1+-+-1%2AD%2F1%29+%2B+-6%5CD+=+10 and simplify: So, we know that D=3. Since G+=+25%2F1+-+-1%2AD%2F1, G=28.

Answer: system%28+G=28%2C+D=3+%29.
