Question

This year 116 kangaroos were adopted from a shelter. This is 24 fewer than twice the number that were adopted last year. Write an equation that you can use to find the number of pets adopted last year?​

Answer 1

70

Explanation:

Let x be the number of kangaroos adopted last year.

Twice the number adopted last year is 2x.

So, the number adopted this year is 2x - 24.

Equating this to the given number of kangaroos adopted this year, we have:

2x - 24 = 116

Adding 24 to both sides, we get:

2x = 140

Dividing both sides by 2, we get:

x = 70

So, the number of kangaroos adopted last year was 70.
