The correct Answer is:
To solve the equation \((4x + 3, y) = (3x + 5, -2)\), we can break it down into two separate equations by equating the corresponding components. ### Step 1: Set up the equations From the given equation, we can derive two equations: 1. \(4x + 3 = 3x + 5\) 2. \(y = -2\) ### Step 2: Solve for \(x\) Now, we will solve the first equation for \(x\): \[ 4x + 3 = 3x + 5 \] Subtract \(3x\) from both sides: \[ 4x - 3x + 3 = 5 \] This simplifies to: \[ x + 3 = 5 \] Now, subtract \(3\) from both sides: \[ x = 5 - 3 \] Thus, we find: \[ x = 2 \] ### Step 3: Find the value of \(y\) From the second equation, we already have: \[ y = -2 \] ### Step 4: Calculate the sum of \(x\) and \(y\) Now, we need to find the sum \(x + y\): \[ x + y = 2 + (-2) \] This simplifies to: \[ x + y = 0 \] ### Final Answer The sum of the values of \(x\) and \(y\) is \(0\). ---
