Question

A number is added to 4.

The result is then multiplied by 3 to
give a new result of 33. What is the number?

Answer 1

7

Explanation:

1. Translate the statement into an equation:

• 
  `(n+4)*3=33`

2. Simplify both sides of the equation.

• 
  `n(3) + 4(3) = 33`

• 
  `3n + 12 = 33`

3. Subtract 12 from both sides.

• 
  `3n + 12 - 12 = 33 - 12`
• 
  `3n = 21`

4. Divide both sides by 3.

• 
  `(3n)/(3) = (21)/(3)`
• 
  `n = 7`

Answer 2

it's 7, right?

Explanation:

if you do it backwards it's 33÷3 which is 11 (only whole number that goes into 33)

then 11-4 is 7
