Answer:

#x=6#

Another way of looking at it!

Explanation:

The you need to get one #x# on its own on one side of = and everything else on the other side.

This is how you do it for your question:

When multiplying, change what you want to get rid of into 1 as anything multiplied by 1 does not change.

#color(blue)("Method for getting rid of the 2 on the left.")#

Divide both sides by 2

#color(brown)(2x) -: 2=color(brown)(12) -:2#

#color(green)("If you divide one side of = by any number you have to")#
#color(green)("divide the other side by the same number")#

Write as: #2/2 xx x=12/2#

but #2/2# is 1

#1xxx=6#

#x=6#
