All we have to do here is to express numbers 40 and 5 in each of equations. Note that first number in brackets is always x coordinate and second number is y coordinate
First equation: 5 = 40*8 false
Second 5 = 5*40 false again
Third: 5 = 40/8 = 5 True
checking for just in case last one: 5 = 40/5 = 8 False
