You can put this solution on YOUR website!
You have a good start. Now take the equation you re-wrote and multiply all sides times -2:
\n" ); document.write( "3x-4y=13
\n" ); document.write( "= -6x+8y= -26 Now add:
\n" ); document.write( " 6x+5y = 52
\n" ); document.write( "+-6x+8y=-26
\n" ); document.write( "--------------
\n" ); document.write( " 13y= 26; y= 2
\n" ); document.write( "Now we solve for x:
\n" ); document.write( "3x-4(2)= 13
\n" ); document.write( "3x-8= 13
\n" ); document.write( "3x= 21
\n" ); document.write( "x= 7
\n" ); document.write( "Let's see if we're right, let's plug these numbers into the other equation:
\n" ); document.write( "6(7)+5(2)= 52
\n" ); document.write( "42+10=52 We've got the right answer. \n" ); document.write( "

\n" );
