Final answer:
To solve for b, simplify both sides of the equation by combining like terms and isolate b by performing the necessary operations.
Step-by-step explanation:
To solve for b in the equation 3.5b + (-8) = (-6.25b) - 6.5, we can start by simplifying both sides of the equation.
First, we can combine like terms:
3.5b + (-8) = (-6.25b) - 6.5
3.5b - 8 = -6.25b - 6.5
Combine like terms:
9.75b - 8 = -6.5
Add 8 to both sides:
9.75b = 1.5
Divide both sides by 9.75:
b = 0.1538
