3x - 5 = 17
3x + 5 = 17
5x - 3 = 17
5x + 3 = 17

Answer 1

3x+5=17 that's the answer

Answer 2

The correct option is B)
`3x+5=17`.

Explanation:

Consider the provided information.

Mike's age is five more than three times his sister's age. Mike is seventeen years old.

Let Mike's sister age is x.

Five more than three times his sister's age can be written as:

`5+3x`

`3x+5`

Mike is seventeen years old.

`3x+5=17`

Hence, the required equation is
`3x+5=17`.

Thus, the correct option is B)
`3x+5=17`.
