The correct Answer is:
To solve the equation \((4x + 5) : (3x + 11) = 13 : 17\), we will follow these steps: ### Step 1: Set up the equation We can express the ratio as a fraction: \[ \frac{4x + 5}{3x + 11} = \frac{13}{17} \] ### Step 2: Cross multiply To eliminate the fractions, we cross multiply: \[ 17(4x + 5) = 13(3x + 11) \] ### Step 3: Distribute on both sides Now, we distribute the numbers on both sides: \[ 68x + 85 = 39x + 143 \] ### Step 4: Move all terms involving \(x\) to one side Subtract \(39x\) from both sides: \[ 68x - 39x + 85 = 143 \] This simplifies to: \[ 29x + 85 = 143 \] ### Step 5: Move the constant to the other side Subtract \(85\) from both sides: \[ 29x = 143 - 85 \] This simplifies to: \[ 29x = 58 \] ### Step 6: Solve for \(x\) Now, divide both sides by \(29\): \[ x = \frac{58}{29} \] This simplifies to: \[ x = 2 \] ### Final Answer The value of \(x\) is \(2\). ---
