First, distribute the -3 across the parentheses: $9x - 3x - 3y = y - x$. Simplify to get $6x - 3y = y - x$. Add $3y$ and $x$ to both sides to get $7x = 4y$. Finally, solve for $y$ to get $y = \frac{7}{4}x$.

Solve for Y 9x−3(x+y)=y−x9 x - 3 ( x + y ) = y - x9x−3(x+y)=y−x

Solve for Y $9 x - 3 ( x + y ) = y - x$
