Question

y - x² = 18 - 20x

Explanation:

Assuming we want to solve for \( y \) in terms of \( x \) (rearrange the equation):

Step 1: Isolate \( y \)

To solve for \( y \), we add \( x^2 \) to both sides of the equation \( y - x^2 = 18 - 20x \).
\( y - x^2 + x^2 = 18 - 20x + x^2 \)

Step 2: Simplify

Simplifying both sides, the \( -x^2 \) and \( +x^2 \) on the left cancel out.
\( y = x^2 - 20x + 18 \)

Answer:

\( y = x^2 - 20x + 18 \)
