Two equal sides = x
\n" ); document.write( "Third side = 2x - 15
\n" ); document.write( "Perimeter = x + x + (2x - 15)
\n" ); document.write( "53 = x + x + 2x - 15
\n" ); document.write( "Collect like terms
\n" ); document.write( "4x = 53 + 15
\n" ); document.write( "4x = 68
\n" ); document.write( "x = 17
\n" ); document.write( "Two equal sides = 17 inches
\n" ); document.write( "Third side = 19 inches.
