Extra words because my answer was too short LOL
12. 10+ x = 5 (1/5x + 2)
13. 8 (x + 2) = 2x + 16
14. 3+ 3/2x + 4 = 4x – 5/2x
15. 3/2 (2x +6) = 3x +9
16. ½ (2-4x) +2x = 13
17. 12 + 2x – x = 9x +6
18. 4x +1 = 2 (2x + 3)
19. 4 (x + 3) - 4 = 8(½x + 1)
20. X + 5x + 4 = 3(2x – 1)
21. 5 (x + 2) - 3x = 2 (x +5)

Step-by-step explanation:
The subject of this question is Mathematics at a High School level. The length of the room is twice the width.
The subject of this question is Mathematics and it is at a High School level.
Let the width of the room be represented by w.
Then, the length of the room would be 2 times the width, so it can be represented as 2w.
Since we know that the length is twice the width, we can write the equation:
2w = l
To find the length, we substitute the value of the width into the equation:
2w = 2 * w
l = 2w
So, the length of the room is twice the width.

Answer:
45 tickets for the matinee were sold
Step-by-step explanation:
let m represent the number of matinee tickets sold and
let e represent the number of evening tickets sold.
Create a system of equations and solve for m
m + e = 130 → (1) ( total ticket sales )
6m + 10e = 1120 → (2) ( income from tickets sold )
multiplying (1) by - 10 and adding the result to (2) will eliminate e
- 10m - 10e = - 1300 → (3)
add (2) and (3) term by term to eliminate e
(6m - 10m) + (10e - 10e) = 1120 - 1300
- 4m + 0 = - 180
- 4m = - 180 ( divide both sides by - 4 )
m = 45
the number of matinee tickets sold was 45
