Eva spent 2 hours tutoring and 6 hours clearing tables.
Let x represent the number of hours Eva worked tutoring and y represent the number of hours Eva worked clearing tables.
Eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Hence:
y = 3x
-3x + y = 0 (1)
16x + 8y = 80 (2)
Solving equations 1 and 2 simultaneously gives:
x = 2, y = 6
