Question 1187111

"A rectangle’s 102 in perimeter is . Its length is 5 in longer than its width. Use an equation to find the rectangle’s length and width." How do I set up the equation?
<pre>Correct equations: {{{highlight_green(system(matrix(1,3, 2L + 2W, "=", P), and, matrix(1,3, L, "=", W - 5)))}}} 
Reduce the 1st equation to get a simpler one.
Substitute the 2nd into the reduced version of the 1st and solve for W. Then find L, the length.
