Evaluate
2b−72b
Collect like terms by calculating the sum or difference of their coefficients
(2−72)b
Subtract the numbers
−70b
−70b−9=0
Move the constant to the right side
−70b=0+9
Removing 0 doesn't change the value,so remove it from the expression
−70b=9
Change the signs on both sides of the equation
70b=−9
Divide both sides
7070b=70−9
Divide the numbers
b=70−9
