leva [86]

$10 \frac{3}{4} - 7 \frac{1}{4} \\ \\ \frac{10 \times 4 + 3}{4} -7 \frac{1}{4} \\ \\ \frac{43}{4} - y \frac{1}{4} \\ \\ \frac{43}{4} - \frac{7 \times 4 + 1}{4} \\ \\ \frac{43}{4} - \frac{29}{4} \\ \\ \frac{43-29}{4} \\ \\ \frac{14}{4} \\ \\ \frac{7}{2} \\ \\ 3 \frac{1}{2} \\ \\ Answer: \fbox {3 \ 1/2} \ or \ \fbox {3.5}$

Subtract and simplify.

Anestetic [448]

$(y^2-7y-5)-(-3y^2+3y-4)$
$=y^2-7y-5+3y^2-3y+4$
$=3y^2+y^2-7y-3y-5+4$
$=4y^2-10y-1$

In short, the answer would be $4y^2-10y-1$ (Option D).

Hope this helps !
