Answer:
45
Step-by-step explanation:
Lets split the problem then add/subtract at the end
3 x 6 = 18
Due to Order of operations we do 2^3 first then multipy by 4
so 2^3 = 8 Then we do 8 x 4 = 32
Now we add/subtract
18 + 32 - 5 = 45
45 is the answer
Answer:
A 
Step-by-step explanation:
The equation
have in both sides expressions
and 
Therefore, the system of two equations

has the solution (x,y), where x is the solution of the equation above.
