-1/8(2h + 4) + 1/2 = -7/4
-1/4h - 1/2 + 1/2 = -7/4
-1/4h = -7/4
h = -7/4 * - 4
h = 7 <==

Answer: A. 7

Explanation:

The given equation :
(-1)/(8)(2h+4)+(1)/(2)=(-7)/(4)

Multiply 8 on both sides , we get


8*(-1)/(8)(2h+4)+8*(1)/(2)=8*(-7)/(4)


-(2h+4)+4=-14\\\\\Rightarrow\ -2h-4=-14-4\\\\\Rightarrow\ -2h=-18+4\\\\\Rightarrow\ -2h=-14\\\\\Rightarrow\ h=7

Hence, the value of h= 7
