Hey! :)
Let us make these number be x and y.
x + y = 54
x - y = 26
Now, add these equations to get the following:
2x = 54 + 26 = 80
2x = 80
x = 80/2 = 40
Now, x + y = 54 meaning 40 + y = 54.
Therefore y = 54 - 40 = 14.
Have a great rest of your day :)
Step-by-step explanation:
x+y+z= 180 (being sum of three angle of a triangle)
We can solve it algebraically:

(subtract 4 from both sides to isolate


(square both sides to get rid of square root on left side

(divide both sides by 3 to isolate y)
The numbers are complex numbers, and the sum of the complex numbers (-4 +i) and (10 - 5i) is 6 - 4i
<h3>How to evaluate the sum?</h3>
The expressions are given as:
(-4 +i) and (10 - 5i)
The sum is represented as:
Sum = (-4 +i) + (10 - 5i)
Open the brackets
Sum = -4 +i + 10 - 5i
Collect like terms
Sum = -4 + 10 +i - 5i
Evaluate the like terms
Sum = 6 - 4i
Hence, the sum of the complex numbers (-4 +i) and (10 - 5i) is 6 - 4i
