Thu wants to play “Guess My Number,"she states. “When I triple my number and add five ,I get twenty-six.what is my number?" What is her number? Show how you know

Answer 1

26 - 5 = 21

21 / 3 = 7

Answer 2

The correct answer is:

Her number is 7.

Explanation:

Let x represent her number.

She triples her number; this is represented by 3x.

She then adds 5 to this; this gives us 3x+5.

She gets 26 aas her answer. This gives us the equation:

3x+5 = 26

To solve this, first subtract 5 from each side:

3x+5-5 = 26-5

3x = 21

Divide each side by 3:

3x/3 = 21/3

x = 7
