Question

Antony is 30 years older than his daughter. In five years time, Antony will be 4 times as old as his daughter. How old is Antony now?

Answer 1

I got this *like a boss*
let antony = x years old
daughter = y years old

we can find 2 equations
y+30 = x
x+5 = (y+5)*4

now solve the system by plugging x's value into the 2nd equation:
(y+30) +5 = 4y +20
y -4y = 20 - 35
-3y = -15
y = 5
now we know that his daughter is 5 years old

since antony is 30 years older, he is 35 (x=35)
