Question

HELP! Clare asks Andre to play the following number and puzzle:
- Pick a number
- Add 2
- Multiply by 3
- Subtract 7
- Add your original number
Andre’s final result is 27. What number did he start with?

Answer 1

The question is an illustration of equations.

The number he started with is 28/3

How to determine the number

Assume the number is x

Add 2 to the number;

So, the expression becomes:

x + 2

Multiply the expression by 3.

So, we have:

3(x + 2)

Subtract 7 from the expression.

So, we have:

3(x + 2) - 7

The final result is 27.

So, we have:

$3(x + 2) - 7=27$

Add 7 to both sides

$3(x + 2) = 34$

Divide both sides by 3

$x + 2 = \frac{34}3$

Subtract 2 from both sides

$x = \frac{34}3 - 2$

So, we have:

$x = \frac{34 - 6}3$

$x = \frac{28}3$

Hence, the number he started with is 28/3
