#x = 3#

Explanation:

#-3 + 3(x+5) = 6 + 5x#

First, we want to use the distribute property to simplify #3(x+5)#. This means that we "distribute" or multiply the #3# to everything inside the parenthesis. So:
#3 * x = 3x#

#3 * 5 = 15#

and when you combine them you get #3x + 15#. Now let's put this back into the equation:
#-3 + 3x + 15 = 6 + 5x#

Now let's add #-3# to #15#:
#12 + 3x = 6 + 5x#

Now let's subtract #12# on both sides of the equation:
#3x = -6 + 5x#

Then let's subtract #5x# on both sides of the equation:
#-2x = -6#

Finally, let's divide both sides by #-2# to get the value of #x#:
#x = 3#

#x=3#

Explanation:

#-3+3(x+5)=6+5x#

Distributive property
#-3+3x+15=6+5x#

Combine like terms
#12+3x=6+5x#

Subtract #6# from both sides
#6+3x=5x#

Subtract #3x# from both sides
#6=2x#

Divide both sides by #2#
#3=x#
