Question

You have 2 numbers. If you double the first number and add it to another number the sum would be 10. Write an equation using x and y.

Answer 1

2x+y=10

Explanation:

Let's say the first number is x.

We will double that number to get 2x.

Then we add it to y to get 2x+y

This all adds up to 10 so 2x+y=10

Answer 2

2x+y=10

Explanation:

If you're going to double the first number, then add another one, you'd have to multiply either x or y by 2 then add x or y :)
