You can put this solution on YOUR website!
theres a few ways to solve it 2 main ways are by elimination or by substitution
\n" ); document.write( "i find elimination easier and faster
\n" ); document.write( "there are several ways to solve using elimination i try to find the easiest one to eliminate with using the smallest numbers
\n" ); document.write( "im going to eliminate the y variable since 2 goes into 6 3 times and 6 stays a 6
\n" ); document.write( "so multiply the top equation by 3
\n" ); document.write( "\"3%2810x-2y%29=3%284%29\"
\n" ); document.write( "\"30x-6y=12\" <---new first equation
\n" ); document.write( "\"3x-6y=12\" <---original 2nd equation, now subtract the equations like u would an old fasion 3rd grade subtraction problem
\n" ); document.write( "\"%2830x-3x%29%2B%28-6y-%28-6y%29%29=%2812-12%29\"
\n" ); document.write( "\"27x%2B0=0\"
\n" ); document.write( "\"highlight%28x=0%29\"
\n" ); document.write( "\"10x-2y=4\"
\n" ); document.write( "\"10%280%29-2y=4\"
\n" ); document.write( "\"-2y=4\"
\n" ); document.write( "\"highlight%28y=-2%29\"
\n" ); document.write( "
