Question

Zaria wants you to solve this puzzle: “I am thinking of a number. If you divide my number by 2 and subtract 4, you will get 2. What is my number?

Answer 1

Let

x--------> the number

we know that

$\frac{x}{2} -4=2$

solve for x

Adds $4$ both sides

$\frac{x}{2} -4+4=2+4$

$\frac{x}{2}=6$

Multiply by $2$ both sides

$2*\frac{x}{2}=2*6$

$x=12$

therefore

the answer is

the number is $12$

Answer 2

Your answer should be 12 because you would take 2 ( because that is the ending number) and add 4. Then multiply by 2 and it is 12.
    step 1)  2+4=6
    step 2) 6 x 2=12
    step 3) 12=12 you're answer
