The correct Answer is:
To solve the equation \( 6x + 5y = 7x + 3y + 1 = 2(x + 6y - 1) \), we can break it down into two separate equations and solve for \( x \) and \( y \). ### Step 1: Set Up the Equations From the given equation, we can derive two equations: 1. \( 6x + 5y = 7x + 3y + 1 \) 2. \( 7x + 3y + 1 = 2(x + 6y - 1) \) ### Step 2: Simplify the First Equation Starting with the first equation: \[ 6x + 5y = 7x + 3y + 1 \] Rearranging gives: \[ 6x + 5y - 7x - 3y - 1 = 0 \] This simplifies to: \[ -x + 2y - 1 = 0 \] or: \[ -x + 2y = 1 \quad \text{(Equation 1)} \] ### Step 3: Simplify the Second Equation Now, let's simplify the second equation: \[ 7x + 3y + 1 = 2(x + 6y - 1) \] Expanding the right side: \[ 7x + 3y + 1 = 2x + 12y - 2 \] Rearranging gives: \[ 7x + 3y + 1 - 2x - 12y + 2 = 0 \] This simplifies to: \[ 5x - 9y + 3 = 0 \] or: \[ 5x - 9y = -3 \quad \text{(Equation 2)} \] ### Step 4: Solve the System of Equations Now we have two equations: 1. \( -x + 2y = 1 \) 2. \( 5x - 9y = -3 \) From Equation 1, we can express \( x \) in terms of \( y \): \[ -x = 1 - 2y \implies x = 2y - 1 \] ### Step 5: Substitute \( x \) in Equation 2 Substituting \( x = 2y - 1 \) into Equation 2: \[ 5(2y - 1) - 9y = -3 \] Expanding this gives: \[ 10y - 5 - 9y = -3 \] Simplifying: \[ y - 5 = -3 \implies y = 2 \] ### Step 6: Find \( x \) Now that we have \( y = 2 \), substitute it back into the expression for \( x \): \[ x = 2(2) - 1 = 4 - 1 = 3 \] ### Final Answer Thus, the solution to the equations is: \[ x = 3, \quad y = 2 \]

To solve the equation \( 6x + 5y = 7x + 3y + 1 = 2(x + 6y - 1) \), we can break it down into two separate equations and solve for \( x \) and \( y \). ### Step 1: Set Up the Equations From the given equation, we can derive two equations: 1. \( 6x + 5y = 7x + 3y + 1 \) 2. \( 7x + 3y + 1 = 2(x + 6y - 1) \) ### Step 2: Simplify the First Equation ...
