9x + 4= 5x + 20 (alternate interior angles)
9x-5x =20-4
4x = 16
x= 16/4
x= 4
Answer:
€7200
Step-by-step explanation:
20%---------1440
100%----------y
y= 100×1440/20
y= 144000/20
y= €7200
price before decrease= €7200
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
