Answer: 3
Step-by-step explanation: To solve for n in this equation, we want to get n by itself on the left side of the equation.
Since n is being multiplied by 3, to get n by itself, we need to divide by 3 on the left side of the equation. Since we divided by 3 on the left side, we must also divide by 3 on the right side.
On the left side, notice that the 3's cancel out so we are simply left with n. On the right side we have 9 ÷ 3 which is 3.
Therefore, n = 3
Finally, remember to check your answer by substituting a 3 back into the original equation.
So, we have 3 (3) = 9 which is a true statement.
Remember to show all your work when solving equations.
