Enter Equation or Inequality

Solve the following equation

30000-3000y=9000

Solve for y

30000 - 3000y = 9000

Divide each side by 30000

30000y
30000
=
  
-3000
30000

Group constants

Group our constants 30000 and 9000.
subtract 30000 from both sides

-3000y + 30000 - 30000 = 9000 - 30000

Cancel 30000 on the left side:

-3000y = -21000

Divide each side of the equation by -3000

-3000y
-3000
=
  
-21000
-3000

y = 7

Final Answer


y = 7
