Enter Equation or Inequality

Solve the following equation


Solve for s

418 - 2s + 6.50s = 836.50

Group the s terms on the left:

(-2 + 6.5)s = 4.5s

Form modified equation

4.5s + 418 = + 836.5

Group constants

Group our constants 418 and 836.50.
subtract 418 from both sides

4.5s + 418 - 418 = 836.50 - 418

Cancel 418 on the left side:

4.5s = 418.5

Divide each side of the equation by 4.5


s = 93

Final Answer

s = 93

What is the Answer?
s = 93
