Question

What value of h makes the equation true?

−1/8(2h+4)+1/2=−7/4

A. 7
B. 25/16
C. 7/16
D. 25

Answer 1

-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 2

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
