2x+3/3x+4=7/10
\n" ); document.write( "Cross multiply
\n" ); document.write( "10(2x + 3) = 7(3x + 4)
\n" ); document.write( " 20x + 30 = 21x + 28
\n" ); document.write( "Collect like terms
\n" ); document.write( "20x - 21x = 28 - 30
\n" ); document.write( " -x = -2
\n" ); document.write( " x = 2
\n" ); document.write( "Proof:
\n" ); document.write( "2x+3/3x+4=7/10
\n" ); document.write( "2(2) + 3/3(2) + 4 = 7/10
\n" ); document.write( " 7/10 = 7/10
\n" ); document.write( "Hope this helps.
