First, multiply the first equation by -(7/2)
\n" ); document.write( "This gives:
\n" ); document.write( "-7x=(-21/2)y-77/2
\n" ); document.write( "7x=4y+6\r
\n" ); document.write( "\n" ); document.write( "Now we can add them.\r
\n" ); document.write( "\n" ); document.write( "0=(-13/2)y-65/2
\n" ); document.write( "65/2=(-13/2)y
\n" ); document.write( "-65/13=y
\n" ); document.write( "-5=y\r
\n" ); document.write( "\n" ); document.write( "Now for x:
\n" ); document.write( "7(x)+20=6
\n" ); document.write( "7x=-14
\n" ); document.write( "x=-2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "check:
\n" ); document.write( "-4 =? -4
\n" ); document.write( "-14+20=6\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
