The given equation is
[tex]5-5x=54+3x[/tex]First, we subtract 3x on each side
[tex]\begin{gathered} 5-5x-3x=54+3x-3x \\ 5-8x=54 \end{gathered}[/tex]Second, we subtract 5 on each side
[tex]\begin{gathered} 5-8x-5=54-5 \\ -8x=49 \end{gathered}[/tex]At last, we divide the equation by -8
[tex]\begin{gathered} \frac{-8x}{-8}=\frac{49}{-8} \\ x=-\frac{49}{8} \end{gathered}[/tex]
