Answer:
x = 12
Step-by-step explanation:
When y = 16, to solve for x we can write:
16 = 25/6x - 34
50 = 25 / 6 x (Add 34)
x = 12 (Divide by 25/6)

Answer:
1/3
Step-by-step explanation:
add them together then divide the total by how many there are
We have been given a polynomial and we are asked to factor our polynomial by double grouping.

First of all we will group terms with common factors. We can see that
and 2x have a common factor x. Common factor of -3x and -6 is -3.


Now we will factor out Greatest Common Factor from each group.
After factoring out GCF from each group we got (x+2) as our common binomial. Now we will write our polynomial as a product of two binomials as:
Therefore, our polynomial as a product of two binomials will be
.
Insert y in the second equation and solve for x:
4x+(x^2-8)=-8
4x+x^2-8=-8
4x+x^2=0
x^2+4x=0
x = -4
Now you insers this x-value in the first or second equation (i use the first):
y=(-4)^2-8=16-8=8
Therefore the conclusion must be x=-4 and y=8
