14) -13.9 + \\frac{b}{12.8} = -13.306

14) -13.9 + \\frac{b}{12.8} = -13.306

14) -13.9 + \\frac{b}{12.8} = -13.306

Answer

Explanation:

Step1: Isolate the fraction term

Add 13.9 to both sides of the equation: $\frac{b}{12.8}=-13.306 + 13.9$.

Step2: Calculate the right - hand side

$-13.306+13.9 = 0.594$. So, $\frac{b}{12.8}=0.594$.

Step3: Solve for b

Multiply both sides by 12.8: $b=0.594\times12.8$.

Step4: Calculate the value of b

$b = 7.5932$.

Answer:

$b = 7.5932$
