How to Solve: A Clear, Beginner-Friendly Breakdown
To solve $2x + 3y = 12$ and $x - y = 1$ for $x + y$, begin by isolating one variable using the second equation. From $x - y = 1$, rewrite it as $x = y + 1$. Substitute this expression into the first equation:
$2(y + 1) + 3y = 12$. Expand: $2y + 2 + 3y = 12$. Combine like terms: $5y + 2 = 12$. Subtract 2:
