You can put this solution on YOUR website!
2x-4=x+2
Subtract "x" from both sides to get:
x-4 = 2
Add 4 to both sides to get:
x = 6

You need to get all x terms on one side, everything else on the other side.
Do this using the additive inverse.
a%2B%28-a%29=0
Here's your equation.
2x-4=x%2B2
Let's bring all of the x terms to the left side.
Everything else on the right hand side.
To get rid of x on the right side, add the additive inverse of x or (-x).
Remember whatever you do to one side of the equation, you must do to the other.
2x%2Bhighlight%28-x%29-4=x%2Bhighlight%28-x%29%2B2
%282x-x%29-4=%28x-x%29%2B2
x-4=2
To get rid of the (-4) on the left side, use the additive inverse of (-4).
-(-4) is the same as 4.
Add 4 to both sides of the equation.
x-4%2B4=2%2B4
highlight%28x=6%29
Always check your answer.
2x-4=x%2B2
2%286%29-4=%286%29%2B2
12-4=8
8=8
Your answer led to a true statement.
It's a good answer.
