You can put this solution on YOUR website!
$\"3y=4x%2B5\"$ ... Rearrange this equation to $\"4x-3y=-5\"$
\n" ); document.write( " $\"4x%2B5y=19\"$ --> Equation 1
\n" ); document.write( " $\"4x-3y=-5\"$ --> Equation 2
\n" ); document.write( "------------------------------------------------- Solve these equations by elimination.
\n" ); document.write( "Equation 1 - Equation 2
\n" ); document.write( " $\"8y=24\"$
\n" ); document.write( " $\"y=24%2F8\"$
\n" ); document.write( " $\"y=3\"$ ... Substitute into Equation 1
\n" ); document.write( " $\"4x%2B5%283%29=19\"$
\n" ); document.write( " $\"4x%2B15=19\"$
\n" ); document.write( " $\"4x=4\"$
\n" ); document.write( " $\"x=4%2F4\"$
\n" ); document.write( " $\"x=1\"$
\n" ); document.write( "Therefore, x=1 while y=3. \n" ); document.write( "
