Solve the following equation
450+30d=92d
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
Divide each side by 450
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
