2y-3x=ay-2x for y <br> please solve for y
babunello [35]

Answer:

y= \frac{x}{-a + 2}

Step-by-step explanation:

2y - 3x = ay - 2x

(2y - 3x) + (3x - ay) = (ay - 2x) + (3x - 2y)

2y - 3x + 3x - ay = ay - 2x + 3x - ay

2y - ay = ay - ay -2x + 3x

2y - ay = x

y(-a + 2) = x

\frac{y(-a + 2)}{-a + 2}  = \frac{x}{-a + 2}

y= \frac{x}{-a + 2}

Hope this helps! :D
