84, first you multiply and divide then you add
Since the radius is 12, the equation is
.. x^2 +y^2 = 144
20 less than 1000 is the same thing as 1000 minus 20.
1000 minus 20 is 980.
20 less than 1000 is 980.
2x + 5 = 11
2x = 6
x = 3
y + 4 = 2x + 4
y + 4 = 2(3) + 4
y + 4 = 10
y = 6
answer
x = 3 and y = 6
