Answer:

[tex]x = 3[/tex]

Step-by-step explanation:

[tex]5x-1=3x+5[/tex]

Get the x's on one side.

Add 1:

[tex]5x-1=3x+5\\\box \ \ +1) \ \ (\ \ \ \ +1)[/tex]

[tex]5x=3x+6[/tex]

Subtract 3x from both sides.

[tex]\ \ \ 5x=\ \: 3x+6\\\underline{-3x} \ \ \ \ \underline{-3x}\\[/tex]

[tex]2x = 6[/tex]

Finally, divide both sides by 2.

[tex]2x / 2 = 6/2[/tex]

[tex]x = 3[/tex]
