Question

A number is added to 4.

Answer 1

Answer:

it's 7, right?

Step-by-step 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

Answer 2

Answer:

7

Step-by-step 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.

• $\frac{3n}{3} = \frac{21}{3}$
• $n = 7$
