Move the variable to the left side
−9−b−8b=0
Subtract the terms
More Steps

Evaluate
−b−8b
Collect like terms by calculating the sum or difference of their coefficients
(−1−8)b
Subtract the numbers
−9b
−9−9b=0
Move the constant to the right side
−9b=0+9
Removing 0 doesn't change the value,so remove it from the expression
−9b=9
Change the signs on both sides of the equation
9b=−9
Divide both sides
99b=9−9
Divide the numbers
b=9−9
