Question

solve for x.
r = x + y
x =

Explanation:

Step1: Isolate x

To solve for \( x \) in the equation \( r = x + y \), we need to isolate \( x \) on one side of the equation. We can do this by subtracting \( y \) from both sides of the equation.
\[
r - y = x + y - y
\]

Step2: Simplify

Simplifying the right - hand side of the equation, \( y - y = 0 \), so we have:
\[
x = r - y
\]

Answer:

\( x = r - y \)
