The correct Answer is:
To solve the equation \[ \frac{5}{8} = \frac{-(11 - 7y)}{4y} + \frac{1}{2y} - \frac{1}{8} \] we will follow these steps: ### Step 1: Rewrite the equation The equation is already given in a suitable form. We will work with it as it is. ### Step 2: Find a common denominator The denominators in the right-hand side are \(4y\), \(2y\), and \(8\). The least common multiple (LCM) of these denominators is \(8y\). ### Step 3: Rewrite each term with the common denominator We will rewrite each term on the right-hand side with the common denominator \(8y\): 1. The first term: \[ \frac{-(11 - 7y)}{4y} = \frac{-2(11 - 7y)}{8y} = \frac{-22 + 14y}{8y} \] 2. The second term: \[ \frac{1}{2y} = \frac{4}{8y} \] 3. The third term: \[ -\frac{1}{8} = -\frac{y}{8y} \] Now, we can combine these terms: \[ \frac{-22 + 14y + 4 - y}{8y} = \frac{(14y - y - 22 + 4)}{8y} = \frac{13y - 18}{8y} \] ### Step 4: Set the equation Now we have: \[ \frac{5}{8} = \frac{13y - 18}{8y} \] ### Step 5: Cross-multiply Cross-multiplying gives us: \[ 5 \cdot 8y = 8(13y - 18) \] This simplifies to: \[ 40y = 104y - 144 \] ### Step 6: Rearrange the equation Now, we will rearrange the equation: \[ 40y - 104y = -144 \] \[ -64y = -144 \] ### Step 7: Solve for \(y\) Dividing both sides by \(-64\): \[ y = \frac{-144}{-64} = \frac{144}{64} = \frac{9}{4} \] ### Final Answer Thus, the value of \(y\) that makes the equation true is: \[ y = \frac{9}{4} \] ---
