1. The problem is to rewrite the equation for the variable $I$. 2. To do this, we need the original equation involving $I$. Since it is not provided, let's assume a general linear equation: $$Ax + By = C$$ where $I$ is one of the variables. 3. If $I$ is the variable to isolate, rewrite the equation to solve for $I$. 4. For example, if the equation is $$AI + B = C$$, then isolate $I$ by subtracting $B$ from both sides: $$AI = C - B$$. 5. Next, divide both sides by $A$ to solve for $I$: $$I = \frac{C - B}{A}$$. 6. When dividing, show the cancellation step: $$\cancel{A}I = \frac{C - B}{\cancel{A}}$$. 7. This gives the rewritten equation for $I$ as $$I = \frac{C - B}{A}$$. 8. If you provide the original equation, I can rewrite it specifically for $I$.
