Enter Equation or Inequality

Solve the following equation


Solve for d

450 + 30d = 92d

Group variables

Group our variables 30d and 92d
subtract 92d from both sides

30d + 450 - 92d = 92d - 92d

Cancel 92d on the right side:

-62d + 450 = 0

Group constants

Group our constants 450 and 0.
subtract 450 from both sides

-62d + 450 - 450 = 0 - 450

Cancel 450 on the left side:

-62d = -450

Divide each side of the equation by -62


d = 7.258064516129

Final Answer

d = 7.258064516129

What is the Answer?
d = 7.258064516129
