#### Explanation:

#"using the "color(blue)"distributive property"#

#â€¢color(white)(x)a(b+c)=ab+ac#

#"apply this concept to the brackets on both sides of the"#

#"equation"#

#rArr-3x-15=3x-3#

#"collecting terms in x on the left side and numeric values"#

#"on the right side"#

#"subtract 3x from both sides"#

#-3xcolor(red)(-3x)-15=cancel(3x)cancel(-3x)-3#

#rArr-6x-15=-3#

#"add 15 to both sides"#

#-6xcancel(-15)cancel(+15)=-3color(red)(+15)#

#rArr-6x=12#

#"divide both sides by "-6#

#(cancel(-6) x)/cancel(-6)=12/(-6)#

#rArrx=-2#

#color(blue)"As a check"# Substitute this value into the equation and if both sides are equal then it is the solution.

#"left "=(-3xx3)=-9#

#"right "=(-3xx3)=-9#

#rArrx=-2" is the solution"#

#### Explanation:

If we look at just

So the first side is now

We do the same for the other side resulting in

So now we have

We get all the

We then add

Now we can solve for
