You can put this solution on YOUR website!
solve:
\n" ); document.write( ":
\n" ); document.write( " $\"%283x%29%2F%28x-1%29+%2B+2\"$ = $\"3%2F%28x-1%29\"$
\n" ); document.write( ":
\n" ); document.write( "Multiply equation by (x-1) to eliminate the denominators
\n" ); document.write( "(x-1)* $\"%283x%29%2F%28x-1%29\"$ + 2(x-1) = (x-1)* $\"3%2F%28x-1%29\"$
\n" ); document.write( "cancel out the denominators and you have:
\n" ); document.write( "3x + 2x - 2 = 3
\n" ); document.write( ":
\n" ); document.write( "5x = 3 + 2
\n" ); document.write( "x = $\"5%2F5\"$
\n" ); document.write( "x = 1; but this cannot be the solution, it gives us 0 in the denominators
\n" ); document.write( ":
\n" ); document.write( "It's undefined \n" ); document.write( "
