3x + 4y = 5
\n" ); document.write( "2x + 3y = 4
\n" ); document.write( "Solve this problem using elimination.\r
\n" ); document.write( "\n" ); document.write( "If we multiply both sides of the first equation by 2 and both sides of the second equation by 3 we have:\r
\n" ); document.write( "\n" ); document.write( "6x + 8y = 10
\n" ); document.write( "6x + 9y = 12\r
\n" ); document.write( "\n" ); document.write( "We did this so we would have the same coefficient on x (that is 6). So now we can subtract the second equation from the first eliminating x:\r
\n" ); document.write( "\n" ); document.write( "(6-6)x +(8-9)y = 10-12
\n" ); document.write( "(0)x + (-1)y = -2
\n" ); document.write( "-y = -2
\n" ); document.write( "y = 2\r
\n" ); document.write( "\n" ); document.write( "Now substitute y=2 in either of the original equations and solve for x.\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
