Enter Equation or Inequality

Solve the following equation


Solve for n

n + n + 6 = 36

Group the n terms on the left:

(1 + 1)n = 2n

Form modified equation

2n + 6 = + 36

Group constants

Group our constants 6 and 36.
subtract 6 from both sides

2n + 6 - 6 = 36 - 6

Cancel 6 on the left side:

2n = 30

Divide each side of the equation by 2


n = 15

Final Answer

n = 15

What is the Answer?
n = 15
