You can put this solution on YOUR website!
3x – 7y = 14
\n" ); document.write( "5x + 3y = 9
\n" ); document.write( "in the 2nd equation subtract -5x from both sides. 3y=-5x+9
\n" ); document.write( "divide 3 into both sides. y=(9-5x)/3=3-(5/3)x
\n" ); document.write( "replace y with 3-(5/3)x in the 1st equation. 3x-7(3-(5/3)x)=14
\n" ); document.write( "3x-21+(35/3)x=14
\n" ); document.write( "(9x/3)+(35x/3)=14+21
\n" ); document.write( "44x/3=35
\n" ); document.write( "44x=35*3
\n" ); document.write( "x=105/44
\n" ); document.write( "substitute 105/44 for y in either equation. 5(105/44)+3y=9
\n" ); document.write( "525/44+3y=9
\n" ); document.write( "3y=9-(525/44)=-129/44
\n" ); document.write( "y=-43/44
