Differentiate both sides wrt
:

By the chain rule, we get

Answer:
you would end up at (-4,-1)
Step-by-step explanation:
L = 2W + 1..................(1)
2L + 2W = 74
2L = -2W + 74..............(2) Adding (1) and (2):-
3L = 75
L = 75/3 = 25
W = (25 - 1) / 2 = 12
length is 25 inches and width = 12 inches
