Solve a system of linear equations

Question

A rectangle has a perimeter of 84 inches. The length is 3 more than twice the width. Write and solve a system of linear equations to find the length and the width of the rectangle?

David W. · Accepted Answer

l = 2w + 3
2l + 2w = 84
 
2(2w + 3) + 2w = 84
 
Solve for w, then plug your answer into the first equation to find l.
