Answer:

X = 8

Step-by-step explanation:

Must set the equations equal to each other.

7*8+14+25=95

11*8+7=95

To solve this, I'm assuming that the equations both represent angles:

There is a theorem that states that an exterior angle of a triangle is equivalent to the sum of two remote triangles. Knowing this:

11x + 7 = 7x + 14 + 25

11x + 7 = 7x + 39

4x = 32

x = 8

Divide both sides by -3, and replace x^2 with y. Then

-3x^4+27x^2+1200=0\iff y^2-9y-400=0

Factorize the quadratic in y to get

y^2-9y-400=(y+16)(y-25)=0\implies y=-16,y=25

which in turn means

x^2=-16,x^2=25

But x^2\ge0 for all real x, so we can ignore the first solution. This leaves us with

x^2=25\implies x=\pm\sqrt{25}=\pm5

If we allow for any complex solution, then we can continue with the solution we ignored:

x^2=-16\implies x=\pm\sqrt{-16}=\pm i\sqrt{16}=\pm4i
