C7/5

D5/7

Answer:

D. 5/7

Read Explanation:

4(x1)×(0.5)(32x)=(18)x4^{(x-1)} \times (0.5)^{(3-2x)} = (\frac{1}{8})^{x}

2(2x2)×(1/2)(32x)=(123)x2^{(2x-2)} \times (1/2)^{(3-2x)}=(\frac{1}{2^3})^x

2(2x2)×2(2x3)=23x2^{(2x-2 )}× 2^{(2x-3)} = 2^{-3x}

(2x2)+(2x3)=(3x)(2x-2) + (2x-3) = (-3x)

4x5=3x4x -5 = -3x

7x=5 7x = 5

x=5/7 x = 5/7
