Question

solve for x. 3x - 7y = z

Explanation:

Step1: Isolate the term with x

We start with the equation \(3x - 7y = z\). To isolate the term containing \(x\), we add \(7y\) to both sides of the equation. This gives us \(3x - 7y + 7y = z + 7y\), which simplifies to \(3x = z + 7y\).

Step2: Solve for x

Now, to solve for \(x\), we divide both sides of the equation \(3x = z + 7y\) by 3. So, \(\frac{3x}{3}=\frac{z + 7y}{3}\), which simplifies to \(x=\frac{z + 7y}{3}\).

Answer:

\(x = \frac{z + 7y}{3}\)
