Answer:
x = -12
Step-by-step explanation:
Remember that ax + bx = (a+b)x
-10x + 9x = 12
Add -10x and 9x together
(-10 + 9)x = 12
-x = 12 (-1x is written as -x, just as 1x is written as x)
÷ -1 both sides
x = -12
I hope this helps. Happy studying. :)

Answer:

Step-by-step explanation:
We're given the word ‘STRANCE’ STRANCE happens to be a 7 letterered word. It contains just 2 vowels A and E, with 5 consonants S, T, R, N and C. We're told to arrange in a way that the vowels occupy only the odd places, so in the word, there exist 4 odd places. The 1st, 3rd, 5th and 7th spot.
The two vowels can be arranged in 4P2 ways. This means that the remaining 5 consonants can be arranged among themselves in a 5P5 ways. Using the permutation formula, we know that
P (n, r) = n!/(n – r)!, so
P (4, 2) * P (5, 5) =
4!/(4 – 2)! * 5!/(5 – 5)! =
4!/2! * 5! =
(4 * 3 * 2!)/2! * 5! =
(12 * 2!)/2! * 120 =
(12 * 2)/2 * 120 =
12 * 120 = 1440
