The value of b in the equation is -2
<h3>What is an algebraic equation?</h3>
An algebraic equation is an expression that consists of numbers, variables with their arithmetic operations.
- When solving this kind of algebraic equation, we move the like terms to a side and solve for the variable(unknown).
From the given algebraic equation:
-4b - 5 = 3b + 9
By collecting the like terms, we have:
-4b -3b = 5 + 9
-7b = 14
Divide both sides by (-7)

x = -2
