Here are our two equations:
\n" ); document.write( "(i) $\"4x+%2B+y+=+11\"$
\n" ); document.write( "(ii) $\"1x+%2B+1y+=+2\"$
\n" ); document.write( "step 1 - multiply (i) by -1.
\n" ); document.write( "(iii) $\"-4x+-+1y+=+-11\"$
\n" ); document.write( "(iv) $\"+1x+%2B+1y+=+2\"$
\n" ); document.write( "step 2 - add down to eliminate y.
\n" ); document.write( "(v) -3X = -9 - - > X = 3.
\n" ); document.write( "Step 3 - find y.
\n" ); document.write( "x=3 means y = -1. \n" ); document.write( "

\n" );
