#x=8#

Explanation:

Remember PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
The first thing you should do is distribute. After that try to put the variables on the same side, and the other numbers on the other.

#5x+2=3(x+6)#

#5x+2=3x+18 " "#Distribute first.

#5x+2-3x=3x+18-3x " "#Suntract both sides by #3x#

#2x+2=18#

#2x+2-2=18-2 " "# Subtract #2# from both sides.

#2x=16#

#(2x)/2=16/2 " "# Divide both sides by #2#

#x=8#
