Solved by pluggable solver: SOLVE linear system by SUBSTITUTION

Solve:
\n" ); document.write( "

We'll use substitution. After moving 24*b to the right, we get:
\n" ); document.write( " $\"5%2Aa+=+109.6+-+24%2Ab\"$ , or $\"a+=+109.6%2F5+-+24%2Ab%2F5\"$ . Substitute that
\n" ); document.write( " into another equation:
\n" ); document.write( " $\"16%2A%28109.6%2F5+-+24%2Ab%2F5%29+%2B+24%5Cb+=+171\"$ and simplify: So, we know that b=3.40378787878788. Since $\"a+=+109.6%2F5+-+24%2Ab%2F5\"$ , a=5.58181818181817.
\n" ); document.write( "
\n" ); document.write( " Answer: $\"system%28+a=5.58181818181817%2C+b=3.40378787878788+%29\"$ .
