\"The length of a rectangle is 7 inches more than three times the width. The perimeter is 94 inches. Find the length and width\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = width
\n" ); document.write( "3x + 7 = length {length is 7 more than 3 times width}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Perimeter of a rectangle = 2(width) + 2(length)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x + 2(3x + 7) = 94 {perimeter is 2 x width + 2 x length}
\n" ); document.write( "2x + 6x + 14 = 94 {used distributive property}
\n" ); document.write( "8x + 14 = 94 {combined like terms}
\n" ); document.write( "8x = 80 {subtracted 14 from both sides}
\n" ); document.write( "x = 10 {divided both sides by 8}
\n" ); document.write( "3x + 7 = 37 {substituted 10, in for x, into 3x + 7}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "width = 10 in.
\n" ); document.write( "length = 37 in.
