Answer:
A
Step-by-step explanation:
really ? you need help to calculate the 2 results of
(2 ± 6) / 2
?
one result is
(2 + 6) / 2 = 8/2 = 4
the other result is
(2 - 6) / 2 = -4/2 = -2
there ! that is all there is to it.
is there still something unclear ?

Answer:
Step-by-step explanation:
In order to solve this, we need to assume that the angles involving x are supplementary, and the angles involving y are complementary.
(7x -8) +(13x -32) = 180
20x -40 = 180 . . . . . . . . . collect terms
20x = 220 . . . . . . . . . add 40
x = 11 . . . . . . . . . . divide by 20
__
(10y +22) +(7y) = 90
17y = 68 . . . . . . . . . . . . collect terms, subtract 22
y = 4 . . . . . . . . . . divide by 17
