Question

solve $9 + 4y = -5x + 7y$ for $x$.
$x = \square$

Explanation:

Step1: Isolate terms with x

Subtract \(7y\) and add \(5x\) to both sides: \(9 + 4y - 7y + 5x = -5x + 7y - 7y + 5x\) simplifies to \(9 - 3y + 5x = 0\).

Step2: Solve for x

Subtract \(9 - 3y\) from both sides: \(5x = 3y - 9\). Then divide by 5: \(x = \frac{3y - 9}{5}\) or \(x = \frac{3y}{5} - \frac{9}{5}\).

Answer:

\(\frac{3y - 9}{5}\) (or \(\frac{3y}{5} - \frac{9}{5}\))
