Question

1. The sum of Sam’s and Tom’s ages is 70. Tom is four times as old as Sam. If you let s = Sam’s age and t = Tom’s age then you can use a system of equations. What are Sam’s and Tom’s ages?

Answer 1

tom is 20 years

Sam is 50 years

Step-by-step explanation:

1. s+t= 70
2. 4t=s
3. putting value of s in step 2 from 1
4. 4t=70-t
5. 5t=70
6. t=70/5
7. t=20
8. s=50
