original
\n" ); document.write( "5x-2y=10
\n" ); document.write( "y=3x-5\r
\n" ); document.write( "\n" ); document.write( "5x-2(3x-5)=10
\n" ); document.write( "Remember order of operations and combine like terms.
\n" ); document.write( "5x-6x+10=10
\n" ); document.write( " -10 -10
\n" ); document.write( "5x-6x=0
\n" ); document.write( "-x=0
\n" ); document.write( "/-1 /-1
\n" ); document.write( "x=0
\n" ); document.write( "To find y we then subtitute our found value for x it into the original problem to complete our pair.
\n" ); document.write( "5(0)-2y=10
\n" ); document.write( "0-2y=10
\n" ); document.write( "-2y=10
\n" ); document.write( "/-2 /-2
\n" ); document.write( "y=-5
\n" ); document.write( "our ordered pair is (0,-5)
\n" ); document.write( "To check to see if our answers are correct, then we plug in our answers for our ordered pair into the original equation.
\n" ); document.write( "5(0)-2(-5)=10
\n" ); document.write( "0+10=10
\n" ); document.write( "10=10
