Answer 2

Simplifying 7b + -4 + 3b + 11 + -1b = 0
 
Reorder the terms: -4 + 11 + 7b + 3b + -1b = 0
 
Combine like terms: -4 + 11 = 7 7 + 7b + 3b + -1b = 0
 
Combine like terms: 7b + 3b = 10b 7 + 10b + -1b = 0
 
Combine like terms: 10b + -1b = 9b 7 + 9b = 0
 
Solving 7 + 9b = 0
 
Solving for variable 'b'.
 
Move all terms containing b to the left, all other terms to the right.
 
Add '-7' to each side of the equation.
7 + -7 + 9b = 0 + -7
 
Combine like terms: 7 + -7 = 0 0 + 9b = 0 + -7 9b = 0 + -7
 
Combine like terms: 0 + -7 = -7 9b = -7
 
Divide each side by '9'. b = -0.7777777778 Simplifying b = -0.7777777778
