$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's simplify ~

$\qquad \sf \dashrightarrow \:( - 2 - 5i) - ( - 4 + 6i)$

$\qquad \sf \dashrightarrow \: - 2 - 5i + 4 - 6i)$

$\qquad \sf \dashrightarrow \: - 2 + 4 - 5i- 6i)$

$\qquad \sf \dashrightarrow \:2 - 11i$

Therefore, A is the Correct choice !

8x+5y=24 y=-4x Solve for y and x

Cloud [144]

Answer:

x= -2 and y= 8

Step-by-step explanation:

8x+5y=24-------A

y=-4x---------B

Putting the value of y from B in A

8x+5(-4x)=24

8x +(-20x)= 24

8x-20x=24

-12x=24

x= -24/12

x=-2--------C y =-4(-2)=8
