Yes babe, u r right. If you ever doubt your answer in these kinds of equations then always replace the X (or any variable) with the answer you get at the end. It helps a lot.

5X + 10 - 6X + 3= 6 -2X - 2

5X – 6X+ 10 + 3= 6 -2x - 2

-1X + 13 = 6-2 -2X

-1X + 13 = 4 -2X

-1X + 1X + 13= 4 -2X +1X

13 - 4= 4 -4 -1X

9= -1X

X= -9

Now replace -9 where ever you see X in the actually equation (5X + 10 - 6X + 3= 6 -2X – 2).

Yes, good job!

You can always verify your answer by substituting

x = -9

into your original equation and see that the result is true.

5(-9) + 10 - 6(-9) + 3 = 6 - 2(-9) -2

-45 + 10 + 54 + 3 = 6 + 18 - 2

22 = 22 (True)

This means you answer x = -9 is correct.

Yes.

Let X = -9 and solve the original equation.

5*(-9)+10-6*(-9)+3 = 6-2*(-9)-2
22=22

Yeah, but the way you rewrite it reversing the terms only makes it more confusing.
For example,
6-2x-2, then
6-2-2x
If you do it that way, you'll end up to likely make more mistakes

Looks good to me.

If you want to be sure, plug in -9 for x in the original equation and see if both sides of the equation equal.

Best way to check if you did it right is to substitute the answer back into the original equation and make sure everything turns out correctly.

That's completely correct. Extra kudos to you for doing it properly by adding x to both sides instead of doing the 'move x to the other side' stuff that most people try to pull off.

Well done.

Yes its 100% correct

It looks correct. If there is any doubt, go back and plug your answer in to the original equation and see if it comes out right.
