Answer:
50 grams
Step-by-step explanation:
You simply subtract 70 from 120, and get 50.
2x = 7y
2 Yogurts = $7
4 Yogurts = $14
6 Yogurts = $21
8 Yogurts = $28
10 Yogurts = $35
3x - 8y = 24 --------(1)
y = x - 8 ---------(2)
substitute y in (1)
3x - 8( x - 8) = 24
3x - 8x + 64 = 24
-5x = 24 - 64
-5x = -40
5x = 40
x= 8
substitute x in (2)
y = 2 - 8
y = - 6
