Answer:
x = - 3
Step-by-step explanation:
Given
5x - 4 = x - 16 ( subtract x from both sides )
4x - 4 = - 16 ( add 4 to both sides )
4x = - 12 ( divide both sides by 4 )
x = - 3

Step-by-step explanation:
[tex] \star{ \sf{ \: 5x - 4 = x - 16}}[/tex]
[tex] \text{Step \: 1 \: : \sf{ \: Move \: x \: to \: left \: hand \: side \: and \: change \: its \: sign.}}[/tex]
[tex] \hookrightarrow{ \sf{5x - x - 4 = - 16}}[/tex]
[tex] \text{Step \: 2 \: : \sf{ \: Move \: 4 \: to \: right \: hand \: side \: and \: change \: its \: sign.}}[/tex]
[tex] \hookrightarrow{ \sf{ 5x - x = - 16 + 4}}[/tex]
[tex] \text{Step \: 3 \: : \sf{Collect \: like \: terms}}[/tex]
[tex] \hookrightarrow{ \sf{ 4x = - 16 + 4}}[/tex]
[tex] \text{Step \: 4 \: : \sf{Calculate}}[/tex]
[tex] \text{ \underline{Remember! : }} \sf{ \: The \: \: negative \: and \: positive \: integers \: are \: always \: subtracted \: but \: posses \: the \: sign \: of \: the \: bigger \: integer.}[/tex]
[tex] \hookrightarrow{ \sf{ 4x = - 12}}[/tex]
[tex] \text{Step \: 4 \: : Divide \: both \: sides \: by \: - 6}[/tex]
[tex] \hookrightarrow{ \sf{ \frac{ 4x}{ 4} = \frac{ - 12}{ 4}}} [/tex]
[tex] \text{Step \: 5 \: : Calculate}[/tex]
[tex] \hookrightarrow{ \sf{x = -3}}[/tex]
The value of x is -3 .
Hope I helped!
Best regards! :D
