Answer 1

S = 3h
s = 10 +2h

3h = 10 + 2h
h = 10

s = 3 × 10
s = 30

Answer 2

Answer:

Sam is 30 years old, and Harry is 10 years old.

Step-by-step explanation:

Let us assume that the age of Sam is x and the age of Harry is y.

Sam is currently is three times Harry's age.

So, $x=3y$  ----------------------1

Sam's age is also 10 more than twice Harry's age.

so, $x=2y+10$  ---------------2

Subtracting 2 from 1, we get

$\Rightarrow x-x=3y-2y-10$

$\Rightarrow 0=y-10$

$\Rightarrow y=10$

putting this in equation 1,

$x=3(10)=30$

Therefore, Sam is 30 years old, and Harry is 10 years old.
