Answer:

holy this is just substitution child

Step-by-step explanation:

1. y + 2, y = 4

if y is equal to 4, we can replace y in the equation

4 + 2 = 6

2. 6a / 3, a = 3

6 * 3 / 3 = 6

4. x - 7, x = 12

12 - 7 = 5

5. 2c - 4, c = 5

2 * 5 - 4 = 6

7. 2z - 3x

2 (8) - 3(5) =

16 - 15 = 1

8. 6x / (y + z)

(6 * 5) / (2 + 8)

30 / 10 = 3
