Question

Bob's age is 4 times greater than Susanne age. Dakota is three years younger than Susanne. the sum of bobs , Susanne's , and Dakota's ages is 93. what is Susanne's age​

Answer 1

Susanne is 16 years old.

Explanation:

You're gonna need three equations.

Key: B = Bob, D = Dakota, s = Susanne

B = 4s

D = s - 3

B + D + s = 93

Now plug in B and D into the third equation:

4s + (s - 3) + s = 93

Now solve it:

4s + s - 3 + s = 93

6s - 3 = 93

+3 +3

6s = 96

6s/6 = 96/6

s = 16
