Answer:
x=-1/6
Alternate form
x=-0.16, x=6^-1
Step-by-step 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
