Answer:
The son is 12 and the father is 33
Explanation:
let f = the father's current age
let s = the son's current age
f - 5 = 4(s-5)
f + s = 45 → f = 45-s
Substitute 45 - s into the first equation for f
45 - s - 5 = 4(s -5) Combine like terms and distribute the 4
40 -s = 4s - 20 Add s to both sides
40 = 5s - 20 Add 20 to both sides
60 = 5s Divide both sides by 5
12 = s
The son is 12 years old.
f + s = 45 Substitute 12 for s and solve for f
f + 12 = 45 Subtract 12 from both sides
f = 33
The father is 33 years old.
