Answer:

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


Hope this helps! :D
Can I have brainliest? :)
Y^2-9^2
(y-9)(y+9)
To see if its right:
y*y+y*9-9*y-9*9
y^2+9y-9y-81
y^2-9^2
Answer:
