To make \( x \) the subject of the equation \( \frac{x}{n} + 2 = w \), follow these steps:
-
Start with the equation: \[ \frac{x}{n} + 2 = w \]
-
Subtract 2 from both sides: \[ \frac{x}{n} = w - 2 \]
-
Multiply both sides by \( n \) to isolate \( x \): \[ x = n(w - 2) \]
So, the solution is: \[ x = n(w - 2) \]
