Simplify
−30−d103
Reduce fractions to a common denominator
−d30d−d103
Write all numerators above the common denominator
d−30d−103
Use b−a=−ba=−ba to rewrite the fraction
−d30d+103
−d30d+103=0
Rewrite the expression
d−30d−103=0
Cross multiply
−30d−103=d×0
Simplify the equation
−30d−103=0
Move the constant to the right side
−30d=0+103
Removing 0 doesn't change the value,so remove it from the expression
−30d=103
Change the signs on both sides of the equation
30d=−103
Divide both sides
3030d=30−103
Divide the numbers
d=30−103
Use b−a=−ba=−ba to rewrite the fraction
d=−30103
Check if the solution is in the defined range
d=−30103,d=0
Solution
d=−30103
Alternative Form
d=−3.43˙
