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
