Solve the equation. If necessary, round your answer to the nearest tenth. x2 = 324
x × w = 324
First, regroup terms. / Your problem should look like: 2x = 324.
Second, divide both sides by 2. / Your problem should look like: x = \(\frac{324}{2}\) .
Third, simplify \(\frac{324}{2}\) to 162. / Your problem should look like: x = 162.
Original answer: x = 162.
Rounded to the nearest tenth: x = 160.
Dividing 2 on both sides of the equal sign will give you x=162 ; rounding it is 160.
