Question

Solve. -1/8c=2 a. 4 b. –16 c. –4 d. 16

Answer 1

$\frac{-1}{8c} =2$
This requires that  c ≠ 0 , meaning c≠0
$\frac{-1}{8c} =2$
Multiply by x to eliminate var in denominator
$\frac{ \not c*(-1)}{ 8 \not c} =c*2$
$\frac{-1}{8} =c*2$
Common denominator  is 8 
$\frac{\not 8(-1)}{\not 8} =8c*2$
$-1=8c*2$
$-1=16c$
$x=-16$
The answer is: b. -16
