Okay. The first step is to add 2 to both side of the equation.

Okay
Katrin369:
4x-2+2=-14
4x-2+2=-14+2
Katrin369:
Now whats the second step?
carmelle:
This is our equation: 4x − 2 = −14
First we add 2 from both sides
4x − 2 = −14
+ 2 = + 2
What are we left with when we do this?

were you get 2 froM.

we have to cancel out the `-2` that is in the equation so that we can get `x` by itself.

what are we left with now?

Do you need more help?
TaeJ:
ok so 4x-2=14 basically 14-2.......find what 14-2 is........
TaeJ:
so do14-2

carmelle:
4x − 2 = −14
+ 2 = + 2
So, what do you get when you do
-2 + 2 = ?
-14 + 2 = ?
TaeJ:
then divide the answer by 4

we have to `add` both sides by 2 not subtract
Tonycoolkid21:
-14+2=-12
carmelle:
Correct, and when we do -2 + 2, we get 0, so the 2 cancels out.

carmelle:
4x = −12
Now, we have to `divide both sides by 4`
4 ÷ 4 = ?
-12 ÷ 4 = ?
Tonycoolkid21:
1 -3
carmelle:
Thats correct!! x = -3
carmelle:
Great job :D
