Multiply 3 and 8 then you will have your answer
X + Y = 180 so X = 122. W = X = 122. Z = Y = 58
45 - 2t < 32 ( where t is time and you can replace it with x or h if you prefer)
Solving for t you get:
45 - 2t - 32 < 0
45 - 32 < 2t
13 < 2t
13/2 < t
Or the temperature will drop below 32F after 6 and a half hours
