The correct Answer is:
To solve the equations for \( x \) and \( y \), we will follow these steps: ### Step 1: Write down the equations The equations given are: 1. \( 4(x - 3) = 3(y + 3) \) 2. \( 17 - 2x = 8 - (2y + 1) \) ### Step 2: Simplify the first equation Start with the first equation: \[ 4(x - 3) = 3(y + 3) \] Distributing both sides: \[ 4x - 12 = 3y + 9 \] Rearranging gives: \[ 4x - 3y = 21 \quad \text{(Equation 1)} \] ### Step 3: Simplify the second equation Now simplify the second equation: \[ 17 - 2x = 8 - (2y + 1) \] This simplifies to: \[ 17 - 2x = 8 - 2y - 1 \] Which further simplifies to: \[ 17 - 2x = 7 - 2y \] Rearranging gives: \[ 2x - 2y = 10 \quad \text{(Equation 2)} \] We can simplify this by dividing everything by 2: \[ x - y = 5 \quad \text{(Equation 2)} \] ### Step 4: Solve the system of equations Now we have the following system of equations: 1. \( 4x - 3y = 21 \) 2. \( x - y = 5 \) From Equation 2, we can express \( x \) in terms of \( y \): \[ x = y + 5 \] ### Step 5: Substitute \( x \) in Equation 1 Substituting \( x \) in Equation 1: \[ 4(y + 5) - 3y = 21 \] Expanding gives: \[ 4y + 20 - 3y = 21 \] Combining like terms: \[ y + 20 = 21 \] Subtracting 20 from both sides: \[ y = 1 \] ### Step 6: Substitute \( y \) back to find \( x \) Now substitute \( y = 1 \) back into Equation 2: \[ x - 1 = 5 \] Adding 1 to both sides gives: \[ x = 6 \] ### Final Solution The solution to the system of equations is: \[ x = 6, \quad y = 1 \]
