#x=2#

Explanation:

#8x + 6 -5x =12#

#3x + 6 = 12#

Subtract #6# from left and right

#3x + 6 - 6 = 12 - 6#

#3x=6#

Then divide both sides by #3#

#(3x)/3=6/3#

#x=2#

#x=2#

Explanation:

First, you should combine your like terms. Note how you have #8x# and #-5x#. Since these two terms have matching variables and matching exponents, you can add them together.

#(8x+(-5x))+6=12# Simplify.
#3x+6=12#

Next, you balance the equation. Remember that in order to do this, you run down PEMDAS, but in reverse. So first, we subtract six from both sides.

#3x+6-6=12-6# Simplify.
#3x=6#

Now all you have left is multiplication, the inverse of which is division. Divide both sides by 3.

#"3x"/3=6/3# Simplify.

#x=2#
