ok our two numbers are x and y
\n" ); document.write( ":
\n" ); document.write( "x+y=64....eq 1
\n" ); document.write( "x-y=4.....eq 2
\n" ); document.write( ":
\n" ); document.write( "rewrite eq 2 to x=4+y and plug that value into eq 1
\n" ); document.write( ":
\n" ); document.write( "(4+y)+y=64
\n" ); document.write( ":
\n" ); document.write( "2y=60.....subtracted 4 from both sides and combined like terms
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28y=30%29\"divided by 2 on each side to isolate variable y
\n" ); document.write( ":
\n" ); document.write( "x=4+y\"highlight%28x=4%2B30=34%29\"
\n" ); document.write( "
\n" );
