x - 4y = 4
-3x - 4y = 12
Subtract the first equation from the second
x - 4y = 4
-4x = 12
Divide the second equation by (-4)
x - 4y = 4
x = -3
Subtract the second equation from the first
- 4y = 7
x = -3
Divide the first equation by (-4)
y = -7/4
x = -3
<h3>
So, the solution is x = -3 and y = - 7/4</h3>
Using complex numbers concepts, it is found that the statement is false.
When a complex number is a root of a polynomial function, it's conjugate also has to be.
- A complex number has the format , and it's conjugate is .
In this problem:
- Real root -3.
- Complex-conjugate roots 1 + i and 1 - i.
- Complex root -3 + 7i.
The conjugate of -3 + 7i also has to be a root, which would make the polynomial of the 5th degree, as it would have 5 roots, thus, the statement is false.
