Question

Answer 1

Okay well first I would add 7 to 83+7=90 then I would divide 90 by 3 because it said three times my number, 90÷3=30 ANSWER: 30 is my number. CHECK: 30×3=90 90-7=83

Answer 2

The number is 30.

Explanation:

Let the number be = x

Tripling this number we get = 3x

When I triple my number and subtract seven I get 83, we can write this mathematically as;

`3x-7=83`

Solving for x, we get;

`=> 3x=83+7`

`=> 3x=90`

`=> x = 90/3`

x = 30

Hence, my number is 30.
