Equate the elements of the matrices,
\n" ); document.write( "11. $\"4=4x-4\"$
\n" ); document.write( "12. $\"4=7-10t\"$
\n" ); document.write( "21. $\"8=4x\"$
\n" ); document.write( "22. $\"7.5=15t%2B1.5x\"$
\n" ); document.write( "Choose the most convenient ones, I guess.
\n" ); document.write( "From 21,
\n" ); document.write( " $\"4x=8\"$
\n" ); document.write( " $\"x=2\"$
\n" ); document.write( "From 12,
\n" ); document.write( " $\"7-10t=4\"$
