Answer:

x=-1/6

Alternate form

x=-0.16, x=6^-1

Explanation:

3(4-x)=13+3x

Distribute 3 through the parentheses

12-3x=13+3x

Move the variable to the left-hand side and change its sign

12-3x-3x=13

-3x-3x=13-12

collect like terms

-6x=13-12

-6x=1

Divide both sides of the eqation by -6

x=-1/6

Alternate form

x=-0.16, x=6^-1
