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?
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
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 \(12\)
