Answers

Answer: x = -8

Step-by-step explanation:

1. Miltiply x-10 on both sides: 396 = -22(x - 10)

2. Distribute -22 to (x - 10): 396 = -22x + 220

3. Subtract 220 from 396: 176 = -22x

4. Divide both sides by -22 to get x by itself: x = -8

Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.

Answers

Answer:

adult tickets  6.9

children tickets  3.9

Step-by-step explanation:

3x + y = 24.60    L1

5x + 4y = 50.10  L2

5L1 - 3L2

15x +  5y = 123

-15x - 12y = -150.3

-7y = -27,3

y = -27,3/-7

y = 3.9

3x + y = 24.60

3x + 3.9 = 24.60

3x = 24.60 - 3.9

3x = 20.7

x = 20.7 / 3

x = 6.9
