__ 7b+(9a-7b^2)/(b) upara=-16,b=-3

To solve the expression \(7b + \frac{9a - 7b^2}{b}\) given \(a = -16\) and \(b = -3\), follow these steps:<br /><br />1. Substitute the values of \(a\) and \(b\) into the expression:<br /> \[<br /> 7(-3) + \frac{9(-16) - 7(-3)^2}{-3}<br /> \]<br /><br />2. Simplify each term:<br /> \[<br /> 7(-3) = -21<br /> \]<br /> \[<br /> 9(-16) = -144<br /> \]<br /> \[<br /> (-3)^2 = 9<br /> \]<br /> \[<br /> 7 \cdot 9 = 63<br /> \]<br /><br />3. Substitute these simplified values back into the expression:<br /> \[<br /> -21 + \frac{-144 - 63}{-3}<br /> \]<br /><br />4. Combine the terms in the numerator:<br /> \[<br /> -144 - 63 = -207<br /> \]<br /><br />5. Now the expression is:<br /> \[<br /> -21 + \frac{-207}{-3}<br /> \]<br /><br />6. Simplify the fraction:<br /> \[<br /> \frac{-207}{-3} = 69<br /> \]<br /><br />7. Finally, combine the terms:<br /> \[<br /> -21 + 69 = 48<br /> \]<br /><br />So, the value of the expression is \(48\).
