The correct Answer is:
To solve the equation \( \frac{4(y+2)}{5} = 7 + \frac{5y}{13} \), we will follow these steps: ### Step 1: Eliminate the fractions Multiply both sides of the equation by the least common multiple (LCM) of the denominators, which is 65. \[ 65 \cdot \frac{4(y+2)}{5} = 65 \cdot \left(7 + \frac{5y}{13}\right) \] ### Step 2: Simplify both sides Distributing on both sides: \[ 13 \cdot 4(y+2) = 65 \cdot 7 + 5 \cdot 5y \] This simplifies to: \[ 52(y + 2) = 455 + 25y \] ### Step 3: Expand the left side Distributing \(52\) on the left side: \[ 52y + 104 = 455 + 25y \] ### Step 4: Move all \(y\) terms to one side and constant terms to the other side Subtract \(25y\) from both sides and subtract \(104\) from both sides: \[ 52y - 25y = 455 - 104 \] This simplifies to: \[ 27y = 351 \] ### Step 5: Solve for \(y\) Divide both sides by \(27\): \[ y = \frac{351}{27} \] ### Step 6: Simplify the fraction Calculating \( \frac{351}{27} \): \[ y = 13 \] Thus, the solution to the equation is: \[ \boxed{13} \] ---
