(a+bi)(2+3i)-i=(-11+5i)(1-i)
2a+3ai+2bi+3bi²-i=-11+11i+5i-5i²
2a+(3a+2b-1)i-3b=-11+16i+5
(2a-3b)+(3a+2b-1)i=-6+16i
Therefore; we have the next system of equations:
2a-3b=-6
3a+2b-1=16
Finally, the system of equations is:
2a-3b=-6
3a+2b=17
We can solve this system of equations by reduction method
2(2a-3b=-6)
3(3a+2b=17)
----------------------
13a=39 ⇒a=39/13=3
3(2a-3b=-6)
-2(3a+2b=17)
----------------------
-13b=-52 ⇒ b=52/13=4
Answer: a=3; b=4

Answer:
p = 16
Step-by-step explanation:
(p + 2) - 4 = 14
We can just drop the parentheses:_
p + 2 - 4 = 14
p - 2 = 14
Add 2 to both sides:-
p - 2 + 2 = 14 + 2
p = 16
Answer:
$= 15p=250
Step-by-step explanation:
So lets say 15 per guest is represented at p so $= 15p+250
