The given equation is

[tex]x-5=2(4x-3)[/tex]

First, we use the distributive property

[tex]x-5=8x-6[/tex]

We sum 5 on each side

[tex]\begin{gathered} x-5+5=8x-6+5 \\ x=8x-1 \end{gathered}[/tex]

Now, we subtract 8x on each side

[tex]\begin{gathered} x-8x=8x-8x-1 \\ -7x=-1 \end{gathered}[/tex]

At last, we divide the equation by -7

[tex]\begin{gathered} \frac{-7x}{-7}=\frac{-1}{-7} \\ x=\frac{1}{7} \end{gathered}[/tex]

Therefore, the solution is 1/7.
