X = Total # of flowers.
Pink = X/4 Flowers.
Bal. = X - X/4 = 3x/4
Red = 2/5 * 3x/4 = 6x/20=3x/10 Flower.
Yellow = 18
X/4 + 3x/10 + 18 = X
Multiply both sides by 20:
5x + 6x + 360 = 20x
11x - 20x = -360
-9x = -360
X = 40
Pink = X/4 Flowers.
Bal. = X - X/4 = 3x/4
Red = 2/5 * 3x/4 = 6x/20=3x/10 Flower.
Yellow = 18
X/4 + 3x/10 + 18 = X
Multiply both sides by 20:
5x + 6x + 360 = 20x
11x - 20x = -360
-9x = -360
X = 40
