Isolate x term: Given the equation $y(x-1)=z$ , we want to solve for $x$ in terms of $y$ and $z$ . First, we isolate the term with $x$ by dividing both sides of the equation by $y$ : $x - 1 = \frac{z}{y}$
Add $1$ to both sides: Next, we add $1$ to both sides of the equation to solve for $x$ : $\newline$ $x = \frac{z}{y} + 1$
Check for matching option: Now we have the expression for $x$ in terms of $y$ and $z$ . We can check the given options to see which one matches our derived expression: $\newline$ $x = \frac{z}{y} + 1$ $\newline$ The correct option that matches this expression is $\frac{z}{y} + 1$ .
