Answer:
\bold{(D)\ (3)/(4)-(1)/(4)x}

Explanation:


\ \ (3)/(4)-x\bigg((1)/(2)-(5)/(8)\bigg)+\bigg(-(3)/(8)x\bigg)\\\\\\=(3)/(4)\bigg((2)/(2)\bigg)-x\bigg[(1)/(2)\bigg((4)/(4)\bigg)-(5)/(8)\bigg]+\bigg(-(3)/(8)x\bigg)\\\\\\=(6)/(8)-x\bigg((4)/(8)-(5)/(8)\bigg)-(3)/(8)x\\\\\\=(6)/(8)-x\bigg(-(1)/(8)\bigg)-(3)/(8)x\\\\\\=(6)/(8)+(1)/(8)x-(3)/(8)x\\\\\\=(6)/(8)-(2)/(8)x\\\\\\=(3)/(4)-(1)/(4)x\quad \text{(reduced both fractions)}
