So this equation you will be moving all the terms containing x to the left hand of the equation since there are two x's.
Since 12x contains x or variable you will be moving to the left-hand side of the equation by subtracting both sides with 12x.
Then the equation will look like this.
10x+4-12x=-16
Then you move -12x left by 10x
10x-12x+4=-16
Subtract 12x from 10x to get
-2x+4=-16

Understand it so far? @narissa
OpenStudy (narissa):
yes
OpenStudy (narissa):
its -16 right?

Then next you will be moving all the terms that don't contain x to the right-hand side of the equation.
Since 4 doesn't contain the variable to solve for, move it to the right-hand side of the equation by subtracting 4 from both sides
-2x=-6-14
-2x=-20
Or
You subtract -4 from
-2x + 4=-16
-2x=-16-4
Still with equal
-2x=-20
Then you will divide -2x by -2 and -20 by -2. Then -2x will turn into X ( not negative since divided by -2).
x=10

thank u

Then plug it into the equation then they will both equal 104=104
10(10)=4= 12(10)-16
100+4=120-16
104=104

So then 10 is still the right answer for that equation. :D
OpenStudy (narissa):
k so 10 is the answer right?
OpenStudy (narissa):
k i opened a new one

Yes. I just put 10 into that equation to explain it to you and show you proof of it.
OpenStudy (narissa):
k
