How do you do the equation -3(n-5) = 7-4ne

  n = -8

Step-by-step explanation:

We assume you want to solve the equation

  -3(n -5) = 7 -4n

Use the distributive property to eliminate parentheses. Then you have a 3-step linear equation that can be solved in the usual way.

  -3n +15 = 7 -4n . . . . . eliminate parentheses

  n +15 = 7 . . . . . . . . . . . add 4n to both sides

  n = -8 . . . . . . . . . . . . . . subtract 15 from both sides

If the coefficient of n were not 1, then you would divide by that. Here, the "3-step" equation took only 2 steps to solve.

The solution is n = -8.
