Find the roots
d=21
Alternative Form
d=0.5
Evaluate
(d−6)−(−9d−1)
To find the roots of the expression,set the expression equal to 0
(d−6)−(−9d−1)=0
Remove the parentheses
d−6−(−9d−1)=0
Subtract the terms

Add the numbers
10d
10d−6+1
Add the numbers
10d−5
10d−5=0
Move the constant to the right-hand side and change its sign
10d=0+5
Removing 0 doesn't change the value,so remove it from the expression
10d=5
Divide both sides
1010d=105
Divide the numbers
d=105
Solution
d=21
Alternative Form
d=0.5
