Answer:

Using the distributive property. (Answer is n = 3).

Step-by-step explanation:

3(5n - 7) = 24

Solve it by multiplying the 3 and 5, and the 3 and 7, to make it:

15n - 21 = 24

Then, solve the rest of it.

15n -21 + 21 = 24 + 21

15n = 45

15n divided by 15 = 45 divided by 15

n = 3

Answer:

Below!

Step-by-step explanation:

The best way to solve this equation is to use distributive property to simplify the LHS. Once simplified, isolate the variable. Once isolated, divide both sides (If needed). Once divided, your result will be nice and clear. Please seek below for solution of the problem.

  • 3(5n - 7) = 24
  • => 15n - 21 = 24
  • => 15n = 24 + 21
  • => 15n/15 = 24 + 21/15
  • => n = 45/15
  • => n = 3
