Enter Equation or Inequality
  

Solve the following equation

n-12+9+8+2=-5

Solve for n

n - 12 + 9 + 8 + 2 = - 5

Group the constants on the left

-12 + 9 + 8 + 2 = 7

Form modified equation

n + 7 = - 5

Group constants

Group our constants 7 and -5.
subtract 7 from both sides

n + 7 - 7 = -5 - 7

Cancel 7 on the left side:

n = -12

Final Answer

n = - 12
