#19 how do you do the work???!
Semenov [28]

Answer:

x=\frac{1}{3}

Step-by-step explanation:

move the terms with x to the left side of the equation:

add 3x to both sides

3x-1+3x=1

add 3x and 3x

6x-1=1

move all term not containing x to the right side:

add 1 to both sides of the equation

6x=1+1

6x=2

divide each term by 6

\frac{6x}{6}=\frac{2}{6}

x=\frac{2}{6}

simplify the fraction

x=\frac{1}{3}
