Question

Dan was thinking of a number. Dan divides by 5, then adds 3 to get an answer of 3. What was
the original number?

Answer 1

Answer:

The original number was: x = 0

Step-by-step explanation:

Let 'x' be the number

Given that:

Dan first divides it by 5

x/5

Then adds 3

x/5 + 3

To get an answer of 3

x/5 + 3 = 3

now solving the expression

$\frac{x}{5}+3=3$

Subtract 3 from both sides

$\frac{x}{5}+3-3=3-3$

Simplify

$\frac{x}{5}=0$

Multiply both sides by 5

$\frac{5x}{5}=0\cdot \:5$

Simplify

$x=0$

Therefore, the original number was: x = 0
