I did the math on a word document; hopefully, the steps help. Remember to use a graphic calculator to solve it.
Answer:
(1,2)
Step-by-step explanation:
x+4y = 9
2x -4y= -6
Add the equations together
x+4y = 9
2x -4y= -6
-------------------
3x +0y = 3
3x=3
Divide by 3
3x/3 = 3/3
x=1
Now find y
x+4y = 9
1 +4y =9
Subtract 1 from each side
4y = 8
Divide by 4
4y/4 = 8/4
y =2
Irrational roots occurs with its conjugate.
Therefore, -√3 is also root of the function.
The answer is -√3.
