What is the sum of the complex numbers -9 - i and -5 - i? 1. -14 - 2i

2. 14 - 2i

3. 14 + 2i

4. -14 + 2i

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

the answer is $42.96
