a. x = 14
b. x = –8
c. x = –13
d. x = –4

Answer 1

I hope this helps you


8-3x=20


8-20=3x

-12=3x

x= -4

Answer 2

x = -4

Explanation:

Given :
`\log_5 (8-3x)=\log_5 20`

To Find : Value of x

Solution:

`\log_5 (8-3x)=\log_5 20`

`8-3x=20`

`8-3x=20`

`8-20=3x`

`-12=3x`

`(-12)/(3)=x`

`-4=x`

Hence Option d is correct.

x = -4
