You can put this solution on YOUR website!
Solving by elimination means you need to eliminate one of the variables to solve for the other.
\n" ); document.write( "So lets start by eliminating the x;
\n" ); document.write( "-3x+8y=10
\n" ); document.write( "5x+6y=80
\n" ); document.write( "To eliminate the x we need to make both numbers opposite so they cancel out, so we will need to multiply each equation by the number that does that.
\n" ); document.write( "(5)-3x+8y=10
\n" ); document.write( "-15x+40y=50 - eq.1
\n" ); document.write( "(3)5x+6y=80
\n" ); document.write( "15x+18y=240 - eq.2
\n" ); document.write( "Now we will add one equation to the other;
\n" ); document.write( "-15x+40y=50
\n" ); document.write( " 15x+18y=240
\n" ); document.write( "-------------
\n" ); document.write( " 58y=290
\n" ); document.write( " y=5
\n" ); document.write( "Now that we have y, we will plug that into the equation to solve for x;
\n" ); document.write( "5x+6(5)=80
\n" ); document.write( "5x+30=80
\n" ); document.write( "5x=50
\n" ); document.write( "x=10
\n" ); document.write( "Hope you understand
\n" ); document.write( "=) \n" ); document.write( "
\n" );
