Let be the coordinates of point P.
The distance from the x-axis is exactly the y coordinates of point P.
The distance from the point (3,-3) is given by
So, we want
We can square both sides to get
Expanding the squares, we have
So, the final equation is
Using Euclid's algorithm, divide 76 by 24. The result is 3 r 4. Now, divide 24 by the remainder. That result is 6 r 0. Since the remainder is zero, the divisor (4) is the greatest common factor of 76 and 24.
The GCF of 76 and 24 is 4.

Another way to look at it is to factor the two numbers and see what factors they have in common.
76 = 4·19
24 = 4·6
since 6 an 19 have no common factors, 4 is the greatest common factor of 76 and 24.
20% of 120 is 24 so you subtract 24 from 120 which is 96:)
