Find the values of x and y in the following equation. (x+yi)+(4+9i)=9-4i

(X+Yi)+(4+9i)=9-4i

The first step is removing the parenthesis:

X + Yi +4 + 9i = 9-4i 

No lets separate the like terms on both sides:

x +4 = 9
Yi +9i = -4i

We can now solve for X:  
x +4 = 9
Subtract 4 from each side:
x = 9-4
x = 5

Yi+9i = -4i

Subtract 9i from each side:
Yi = -4i-9i
Yi = -13i
Y = -13

X = 5, Y = -13.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
