7x+18=-24
-18 -18
7x=-42
then divide to cancel out multiplication
7x=-42

7 7
x=-6
Take 18 to the other side.
7x + 18 - (18) = -24 - (18)
7x = -42
Divide both sides by 7:
7 and 7 cancels out
x = -6

You get (x - 6)(x + 6) on the top.
On the bottom, you can undistribute (pull out) -7x.
This gives you -7x(x-6) on the bottom.
Now you can cancel like terms in the numerator and denominator.
You can cancel the (x-6).
You can also move the negative sign from the 7x to the (x + 6)
This leaves you with -(x + 6) over 7x, or (6 - x) over 7x.
To find excluded values, all you need to know is that you can't divide by zero under any circumstances, and you can't have a zero on the top in a rational expression.
The only values for x that would make either of these statements true are if x = 0 (7 × 0 = 0 on the bottom), or if x = 6 (6 - 6 +0 on the top)
So the answer is (6 - x) over 7x, x ≠ 0, 6

You said 5/6 - 1/3 n = p (5 - 2n)
Divide each side by (5 - 2n) :
p = (5/6 - 1/3 n) / (5 - 2n) .
That's about all you can do with it.
As you can see, the required value for 'p'
depends on the value of 'n'.
If you want to get rid of those awkward fractions,
I guess you could multiply top and bottom by 6 .
Then you have ...
p = (5 - 2 n) / 6·(5 - 2n) .
Oh, my goodness ! Look at that !
p = 1/6 .
It doesn't even depend on 'n' at all. It's always true,
no matter what 'n' is.
I am surprised.
Answer:
19
Step-by-step explanation:
Let x
Then we have 15 (x + 9) = 420.
We can divide both side by 15, getting x + 9 = 28. Then, we can subtract both sides by 9, getting x = 28 - 9 = 19.
Since there are 15 players and he bought a basketball for each of them, he bought 15 basketballs in total.The price of a basketball costs $9.The total price of all 15 basketballs = $9 * 15 = $135.He spent $420 on uniforms and basketballs, and he spent $135 on basketballs.Thus, he spent $420 - $135 = $285 on uniforms.As he bought a uniform for each of the 15 players, he bought 15 uniforms in total.The price of 15 uniforms is $285.The price of 1 uniform is $285 ÷ 15 = $19.

Step-by-step explanation:
You know that 9 = 10 - 1.
Then 9 of something is equal to 10 of it less one of it. Here, that "something" is four.

Comment on this math
This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.
