The gardeners should buy 54 white hydrangeas and 88 pink hydrangeas altogether.
Step-by-step explanation:
Let,
Number of white hydrangeas = x
Number of pink hydrangeas = y
According to given statement;
In first bed
x+y = 40 Eqn 1
In second bed
2 times the number of white hydrangeas and 3 times the number of pink hydrangeas as in the first bed.
2x+3y=102 Eqn 2
Multiplying Eqn 1 by 2
![2(x+y=40)\\2x+2y=80\ \ \ Eqn\ 3](https://tex.z-dn.net/?f=2%28x%2By%3D40%29%5C%5C2x%2B2y%3D80%5C%20%5C%20%5C%20Eqn%5C%203)
Subtracting Eqn 3 from Eqn 2
![(2x+3y)-(2x+2y)=102-80\\2x+3y-2x-2y=22\\y=22](https://tex.z-dn.net/?f=%282x%2B3y%29-%282x%2B2y%29%3D102-80%5C%5C2x%2B3y-2x-2y%3D22%5C%5Cy%3D22)
Putting y=22 in Eqn 1
![x+22=40\\x=40-22\\x=18](https://tex.z-dn.net/?f=x%2B22%3D40%5C%5Cx%3D40-22%5C%5Cx%3D18)
Number of white hydrangeas altogether = x+2x = 3x = 3(18) = 54
Number of pink hydrangeas altogether = y+3y = 4y = 4(22) = 88
The gardeners should buy 54 white hydrangeas and 88 pink hydrangeas altogether.

Log2 (x - 6)(x - 4) = log2 x
(x-6)(x-4) = x
x^2 - 10x + 24 - x = 0
x^2 - 11x + 24 = 0
(x-3)(x-8) = 0
answer is 8
