The given angles 3 and 4 shares a common arm, therefore the angles are known as Adjacant Angles
The factoring can be done similarly to a quadratic equation thanks to x^4 being the square value of x^2.
<span>x^4 + 6x^2 - 7
x^4</span><span> - x^2</span> + 7x^2 - 7
(x^4 - x^2) + (<span>7x^2 - 7)
</span>x^2(x^2 - 1) + 7(<span>x^2 - 1)
</span>(x^2 + 7)(x^2 - 1)
<span>(x^2 + 7)(x - 1)(x + 1)
</span>
Factored completely we get: <span>(x^2 + 7)(x - 1)(x + 1)</span>

<h2>
Answer: x=-2(-y+4)</h2>
Step-by-step explanation:
-2x+4y=16
Subtract 4y from both sides
-2x+4y-4y=16-4y
Simplify
-2x=16-4y
Divide both sides by -2
-2x/-2=16/-2- 4y/-2
