You can put this solution on YOUR website!
(X-5)/(X+4)=2/7 IF THIS IS THE EQUATION THEN WE HAVE TO CROSS MULTIPLY.
\n" ); document.write( "7(X-5)=2(X+4)
\n" ); document.write( "7X-35=2X+8
\n" ); document.write( "7X-2X=8+35
\n" ); document.write( "5X=43
\n" ); document.write( "X=43/5 ANSWER.
\n" ); document.write( "------------------------------------------
\n" ); document.write( "X-(5/X)+4=2/7 IF THIS IS THE EQUATION THEN:
\n" ); document.write( "(X^2-5)/X+4=2/7
\n" ); document.write( "(X^2-5)/X=2/7-4
\n" ); document.write( "(X^2-5)/X=(2-4*7)/7
\n" ); document.write( "(X^2-5)/X=(2-28)/7
\n" ); document.write( "(X^2-5)/X=-26/7 NOW CROSS MULTIPLY.
\n" ); document.write( "7(X^2-5)=-26X
\n" ); document.write( "7X^2-35+26X=0
\n" ); document.write( "7X^2+26X-35=0USING THE QUADRATIC EQUATION WE GET;
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
