Imagine the stove's weight is x and the freezer's weight is y
We know that
x + y = 370
and
x = 170
To find the weight of the freezer (y)
you subtract the stove weight from the total weight
370 - 170 = 200
the freezer is 200 lbs
I'd assume the inequality you'd be looking for in this question is
stove + freezer > freezer > stove
