If 5x = 20, what is the value of x?

To solve the equation \(5x = 20\), we aim to isolate \(x\). This can be achieved by dividing both sides of the equation by 5. Starting with the equation: \[ 5x = 20 \] Dividing both sides by 5: \[ x = \frac{20}{5} \] Calculating the right side gives: \[ x = 4 \] Thus, the value of \(x\) is 4, confirming that the correct answer is indeed 4. This approach is fundamental in algebra; rearranging equations to isolate variables by performing the same mathematical operation on both sides is a key skill. Performing different operations or miscalculating the division could lead to incorrect values, supporting why \(4\) is the only valid solution for this equation.
