solve for b.\n7b - 15 = 5b - 3\nb =

Explanation:

Step1: Simplify the equation

$$7b - 15 = 5b - 3$$ Subtract (5b) from both sides: $$7b-5b - 15=5b - 5b- 3$$ $$2b-15=-3$$

Step2: Isolate the term with (b)

Add (15) to both sides: $$2b-15 + 15=-3+15$$ $$2b = 12$$

Step3: Solve for (b)

Divide both sides by (2): $$\frac{2b}{2}=\frac{12}{2}$$ $$b = 6$$

Answer:

(6)
