#19 how do you do the work???!

Answer:
[tex]x=\frac{1}{3}[/tex]
Step-by-step explanation:
move the terms with [tex]x[/tex] to the left side of the equation:
add 3x to both sides
[tex]3x-1+3x=1[/tex]
add 3x and 3x
[tex]6x-1=1[/tex]
move all term not containing [tex]x[/tex] to the right side:
add 1 to both sides of the equation
[tex]6x=1+1[/tex]
[tex]6x=2[/tex]
divide each term by 6
[tex]\frac{6x}{6}=\frac{2}{6}[/tex]
[tex]x=\frac{2}{6}[/tex]
simplify the fraction
[tex]x=\frac{1}{3}[/tex]
