1) -8 - 3 x 7 - 4 / -2(-3 - 7 ÷ (-6 + 2))
I got -33/2.5 according to my TI-83.
2) -6√x + 1 - 4y^2 when x = 24 and y = -1
I got -5.

2) assuming the x+1 is all under the square root, it would be sqrt 24+1 or sqrt 25 which is 5 and -6 times 5 is -30
-1 squared is +1, times 4 is -4
so it's -30 - -4 which comes out -30 + 4 or - 26

The 1st should be -29 -4/2.5 = -30.6
The 2nd should -30-4 = -34, assuming (x+1)
Thus you got them both wrong.
