3x-11y=20
\n" ); document.write( "2x=4y+10
\n" ); document.write( ".
\n" ); document.write( "Take a look at the second equation. What do you notice?
\n" ); document.write( "We can see that x can easily be found.
\n" ); document.write( "2x=4y+10
\n" ); document.write( "Divide each side by 2
\n" ); document.write( "X = 2Y + 5
\n" ); document.write( "Now, take the value of X and put it into the first equation.
\n" ); document.write( "3x-11y=20
\n" ); document.write( "3(2Y+5)-11y=20
\n" ); document.write( "Distribute
\n" ); document.write( "6Y+5-11y=20
\n" ); document.write( "Subtract 5 from each side
\n" ); document.write( "6Y-11Y=15
\n" ); document.write( "-5Y = 15
\n" ); document.write( "Divide each side by -5
\n" ); document.write( "Y = -3
\n" ); document.write( ".
\n" ); document.write( "x = 2Y + 5
\n" ); document.write( "x = -6 + 5
\n" ); document.write( "x = -1
\n" ); document.write( ".
\n" ); document.write( "Let's prove it by putting it into the equation above.
\n" ); document.write( "2x=4y+10
\n" ); document.write( "2(-1)=4(-3)+10
\n" ); document.write( "-2 = 12+10
\n" ); document.write( "-2 = -2
\n" ); document.write( "Success! \n" ); document.write( "
\n" );
