Question

solve for x.
z = 2x - y

Explanation:

Step1: Isolate the term with x

We start with the equation \( z = 2x - y \). First, we add \( y \) to both sides of the equation to get rid of the \(-y\) on the right side. So, \( z + y = 2x - y + y \), which simplifies to \( z + y = 2x \).

Step2: Solve for x

Now, we have \( z + y = 2x \). To solve for \( x \), we divide both sides of the equation by 2. So, \( \frac{z + y}{2}=x \), or we can also write it as \( x=\frac{y + z}{2} \).

Answer:

\( x=\frac{y + z}{2} \)
