Question

I don't know how to answer this. ??

Answer 1

The third option is the correct answer

The correct equation is,2(s - 12) + s =87

s= 37

Explanation:

It is given that Ara and Evalyn are collecting stamps

Ara has twice as many stamps as 12 less than the number of stamps Evalyn has.

Together they have total 87 stamps.

To find the correct equation

Let s be the number of stamps in Evalyn.

The number of stamps in Ara = 2(s - 12)

They together have 87 stamps

Therefore the equation become,

2(s - 12) + s = 87

To find the value of s

2(s - 12) + s = 87

2s - 24 + s= 87

3s = 111

s = 37

Therefore the correct answer is 3rd option.

Answer 2

Answer:3rd option s=37

Explanation:

See Ara and Evalyn are collecting stamps.

It is given that Ara has twice of 12 less than the stamps Evalyn has.

And we are given that total no. of stamps is 87.

So, our equation becomes,

2(S - 12) + S = 87

Where 'S' is no. of stamps Evalyn has.

Solving for S, we get,

S = 37

So , first we get to know is Wilmer's equation is incorrect because he has not added no . of stamps Evalyn has which is S

So option 3 is correct

We can also calculate the no. of stamps Ara has which is

2(37 - 12)

= 50

Hope it helps!!!
