W have the following original system:
\n" ); document.write( "(i)-8x-8y=8
\n" ); document.write( "(ii) 5x+y=-5
\n" ); document.write( "step 1 - multiply (ii) by 8 to get
\n" ); document.write( "(iii) 40x + 8y = -40
\n" ); document.write( "step 2 - add (i) and (iii) to get
\n" ); document.write( "32x = -32
\n" ); document.write( "x = -1
\n" ); document.write( "substitute x = -1 into (i) to get
\n" ); document.write( "-8(-1) - 8y = 8
\n" ); document.write( "8 - 8y = 8
\n" ); document.write( "-8y = 0
\n" ); document.write( "y = 0
\n" ); document.write( "OUr answer is
\n" ); document.write( "(-1,0) \n" ); document.write( "
\n" );
