Factor this by grouping. Group the first two terms together and then the second 2 terms together. The idea here is that, after grouping, what you can pull out in both groups is the same. Like this:

Now work on finding a common thing between the 2 groups:

See, what you have in common there now is the (x-9) that you can factor out:

And that is factored completely.

Answer:
X= 11
Step-by-step explanation:
That equation becomes -7x+15x-30 =58
And add them all up giving you 8x-30=58
Add 30 to both sides
8x=88
Divide 88 by 8 which gives you 11
<span> Simplifying
4x + 4y = 0
Solving
4x + 4y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
4x + 4y + -4y = 0 + -4y
Combine like terms:
4y + -4y = 0
4x + 0 = 0 + -4y
4x = 0 + -4y
Remove the zero:
4x = -4y
Divide each side by '4'.
x = -1y
Simplifying
x = -1y</span>
