Answer:
since there is 8 ones on the left and 4 ones on the right as well as the balance being equal we know that X+4 = 8. so that means 8-4=X. use a calculator to figure out 8-4 (The right minus the left)

The length of the AC is x^2 + 4x - 12.
<h3>What is a parallelogram?</h3>
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Given :
In Parallelogram ABCD, diagonals AC and BD intersect at point E.
such that
AE = x^2 - 12,
CE = 4x
We know that the diagonal of a parallelogram bisect each other.
x^2 - 12 = 4x
x^2 - 4x - 12= 0
(x-6)(x-2) = 0
Hence, the value of x = 6, 2.
AC = AE + CE = x^2 + 4x - 12.
The length of the AC is x^2 + 4x - 12.

Hope that helps.
Answer:
see, you take 3y to the other side it becomes 4x=12+3y. then you take out the 4 from X and divide it by 12+3y. so it becomes 12+3y/4
