Answer:

  1. Equation: 3(n - 4) = 18
  2. Solved: n = 10

Explanation:

To solve:

  1. Apply the distributed property: 3n - 12 = 18
  2. Add 12 to each side, so it now looks like this: 3n = 30
  3. Divide each side by 3 to cancel out the 3 next to n. It should now look like this: n = 10

I hope this helps!

Answer:

n = 10

Explanation:

Step 1: Translate word to math

"product" = multiplication

"3" = 3

"difference" = subtraction

"a number n" = n

"4" = 4

"is" means equal

"eighteen" = 18

Step 2: Combine/set up equation

3(n - 4) = 18

Step 3: Solve for n

  1. Distribute 3: 3n - 12 = 18
  2. Add 12 to both sides: 3n = 30
  3. Divide by 3 on both sides: n = 10
