Question

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

Answer 1

`(-1)/(8c) =2`
This requires that c ≠ 0 , meaning c≠0

`(-1)/(8c) =2`
Multiply by x to eliminate var in denominator

`( \\ot c*(-1))/( 8 \\ot c) =c*2`

`(-1)/(8) =c*2`
Common denominator is 8

`(\\ot 8(-1))/(\\ot 8) =8c*2`

`-1=8c*2`

`-1=16c`

`x=-16`
The answer is: b. -16
