75% are full with 20 seats empty so </span>20 seats empty = 25%
75% * 20 / 25% = 60
-4 because -16-4=-4. Negative and a positive make a negative
You would form this inequality:
52 + 2x < (or equal to) 180
Then, solve as you would in an ordinary equation.
Subtract 52 from both sides of the sign. 180 - 52 = 128.
So, 2x is less than or equal to 128.
Divide 128 into two to get 64.
The height of the frame must be 64 inches.
