Answer:

x = 4   y = 2   w = 6   z = 8

Step-by-step explanation:

x + 10y = 24

  - 10y         - 10y

x = 24 - 10y

3x + 7y = 26

3(24 - 10y) + 7y = 26

72 - 30y + 7y = 26

-72                    -72

(-23y) = -46

-23y/-23 = -46/-23

y = 2

x + 10y = 24

x + 10(2) = 24

x + 20 = 24

   - 20   - 20

x = 4

x + y = w

4 + 2 = w

w = 6

w + y = z

6 + 2 = z

z = 8
