Hi there!
Let's us Substitution, as it appears to be the easiest one. We can solve the second equation for y. 
4x - 2y = 2
-2y=-4x+2
y=2x-1
Now that we have found the expression for y, we can substitute it back into the first equation. 
6x + 4y = -8
6x+4(2x-1)=-8
Next, just solve for x. 
6x+4(2x-1)=-8
6x+8x-4=-8
14x-4=-8
14x=-4
x =-\frac{2}{7}
We have found the x-value of the system of equation, now we have to find the y-value. To do this, we can substitute the derived x-value into any equation, I'll be doing it in the first equation. When we substitute -2/7 into the first equation and solve for y, we get -11/7. Therefore, the solutions to the system of equations are -2/7 and -11/7. Hope my answer has come of assistance you and have a phenomenal day!

Alex73 [517]
Answer: \\ {( {x}^{2} + 4) }^{2} + 32 = 12 {x}^{2} + 48 \\ \Leftrightarrow {a}^{2} + 32 = 12( {x}^{2} + 4) \\ \Leftrightarrow {a}^{2} + 32 = 12a \\ \Leftrightarrow {a}^{2} - 12a + 32 = 0 \\ \Rightarrow Coefficients:1, \: -12. \: Constant:a
