You can put this solution on YOUR website!
x+y= 10........eq 1
\n" ); document.write( "x-y= 2.........eq 2
\n" ); document.write( ":
\n" ); document.write( "there is no formula...You are simply adding a system of equations together. This problem is perfectly set up for the y terms to be eliminated. When adding these equations together the x terms are added to the x terms , the y terms are added to the y terms and the constant is added to the constant
\n" ); document.write( ":
\n" ); document.write( "so you would have x+x, which equals 2x: y-y=0(that is why they call it elimination) and 10+2, which =12
\n" ); document.write( ":
\n" ); document.write( "so since the y terms are eliminated we are left with:
\n" ); document.write( ":
\n" ); document.write( "2x=12
\n" ); document.write( ":
\n" ); document.write( " $\"highlight%28x=6%29\"$
\n" ); document.write( ":
\n" ); document.write( "take x's found value of 6 and plug it back into either equation. I choose eq 2
\n" ); document.write( ":
\n" ); document.write( "6-y=2
\n" ); document.write( ":
\n" ); document.write( "-y=-4
\n" ); document.write( ":
\n" ); document.write( " $\"highlight%28y=4%29\"$
\n" ); document.write( ":
