Here are the two equations:
\n" ); document.write( "(i) 1x - 5y = -47
\n" ); document.write( "(ii) -4x - 5y = -37
\n" ); document.write( "multiply (i) by -1 to get
\n" ); document.write( "(iii) -1x + 5y = +47
\n" ); document.write( "(ii) -4x - 5y = -37
\n" ); document.write( "add down and find x.
\n" ); document.write( "(iv) -5x = 10
\n" ); document.write( "x = -2
\n" ); document.write( "solve for y.
\n" ); document.write( "y = 9.
\n" ); document.write( "(-2,9) \n" ); document.write( "

\n" );
