Solve this system of equation algebracally y+x=19-x2 x+y=80
1 answer:
Answer:
The answer is y = 80± and x = ±
Step-by-step explanation:
We need to solve this system of equations algebraically
y + x = 19 - ..............................................(1)
x+y = 80 ...............................................................................(2)
Substituting equation (2) in equation (1)
80 = 19 -
-61 =
x = ±
Where i is the imaginary
Then the value of y = 80±
This is the solution to this system of equations

<h3>How to get a perfect square?</h3>
A perfect square is the product of a number and itself.
As you can see in the example, 16 is a square number. Then let's try to get 16.
To get 16 we can use the difference:
20 - 4
So the first therm needs to be equal to 20, and the second equal to 4.
To write 20 in scientific notation we have:
