The correct Answer is:
To solve the expression \(3x - 4y\) given \(x = 2\) and \(y = 5\), follow these steps: ### Step 1: Substitute the values of \(x\) and \(y\) into the expression. We have: \[ 3x - 4y = 3(2) - 4(5) \] ### Step 2: Calculate \(3(2)\). \[ 3(2) = 6 \] ### Step 3: Calculate \(4(5)\). \[ 4(5) = 20 \] ### Step 4: Substitute these results back into the expression. Now we have: \[ 6 - 20 \] ### Step 5: Perform the subtraction. \[ 6 - 20 = -14 \] ### Final Answer: The value of the expression \(3x - 4y\) when \(x = 2\) and \(y = 5\) is \(-14\). ---
