You can set up an system of equations
x=2y+8
x-y=25

Substitute x in to the second equation
2y+8-y=25
y+8=25
y=17

Substitute the y back in to the first equation.
x=2(17)+8=42

Find the sum of (–4 + i) and (10 – 5i). –3 + 5i –3 – 5i 6 – 4i 6 – 6i
MaRussiya [10]

Answer:

The answer is 6 – 4i

Step-by-step explanation:

Complex values:

Have the following format: a + bi

In which a is the real part and b is the complex part.

Addition:

Suppose we are going to add two complex numbers. We add their real parts, and their complex parts separatly.

So

(–4 + i) + (10 – 5i) = (-4 + 10) + i(1-5) = 6 - 4i

The answer is 6 – 4i
