Answer:
If I'm not mistaken, the answer should be 56.
Step-by-step explanation:
The question is asking you to solve for Y.
So, using the PEMDAS method, simply do what is in the parentheses first.
28(5-9+6)=Y
5-9=-4
28(-4+6)=Y
-4+6=2
28(2)=Y
28(2)=56
56=Y
PEMDAS-
P-Parentheses
E-Exponents
M-Multiplication
D-Division
A-addition
S-Subtraction
Note: M and D are interchangeable, A and S are as well. It simply depends on which of the two come before the other when reading the equation from left to right.
You could also use the Desmos scientific calculator for this, in this equation you wouldn't even have to do any work with it, simply type the equation in (excluding the Y)
It would look like the image below.
