(1/2)x + x + (1/5)y + y = 32
(3/2)x + (6/5)y = 32
Answer: A, C, and E! I just took this on Khan Academy! Please mark me brainliest because it it correct!
24 were of the questione were correct
Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 = 5E + 15
24 = 4E
6 = E
Evie's current age is 6.
