Solve the proportion: 4/(x+1) = 3/(x+2)
\n" ); document.write( "Cross-multiply:
\n" ); document.write( "4(x+2) = 3(x+1)
\n" ); document.write( "4x+8 = 3x+3
\n" ); document.write( "x = -5
\n" ); document.write( "-------------------
\n" ); document.write( "Solve the proportion: x/(x+3) = (x-2)/x
\n" ); document.write( "Cross-multiply:
\n" ); document.write( "x^2 = (x+3)(x-2)
\n" ); document.write( "x^2 = x^2+x-6
\n" ); document.write( "x-6 = 0
\n" ); document.write( "x = 6
\n" ); document.write( "===================
\n" ); document.write( "Solve the proportion: 5/x = 8/15
\n" ); document.write( "x/5 = 15/8
\n" ); document.write( "x = 5(15/8)
\n" ); document.write( "x = 75/8
\n" ); document.write( "=============
