You can put this solution on YOUR website!
Let x be the first number, and y be the second number.
\r
\n" ); document.write( "\n" ); document.write( "We are given
\r
\n" ); document.write( "\n" ); document.write( "\"3x%2B10=y\" and \"x%2By=70\" or
\r
\n" ); document.write( "\n" ); document.write( "\"3x-y=-10\" and \"x%2By=70\"
\r
\n" ); document.write( "\n" ); document.write( "We can solve this system of equations in several ways. We will add the 2 equations together to get
\r
\n" ); document.write( "\n" ); document.write( "\"4x=60\"
\r
\n" ); document.write( "\n" ); document.write( "\"x=15\"
\r
\n" ); document.write( "\n" ); document.write( "Thus, we have
\r
\n" ); document.write( "\n" ); document.write( "\"15%2By=70\"
\r
\n" ); document.write( "\n" ); document.write( "\"y=55\"
\r
\n" ); document.write( "\n" ); document.write( "The two numbers are 15 and 55.
\r
\n" ); document.write( "\n" ); document.write( "You can check this by trying the two numbers in both equations.
