Answer and explanation:

To solve this, you must find what x equals

x + 2x + 7 = 3x - 7 Add together any numbers that can be added on their side

3x + 7 = 3x - 7 Then subtract 7 from both sides to get 3x alone

3x = 3x - 14  Then subtract 3x from both sides to get x

<h3>*The x's cancel each other out so you must have typed the equation wrong. Please check to see any mistakes you may have made*</h3>

Well first things first, you need to add like terms. So now you should have 3x+7 =3x-7. Now already looking at this, i know that there is no answer because the two 3x will cancel out, making the equation into 14=0.

Answer: -418, 728, 446, -429, 1159, -696

Step-by-step explanation:

1. $n = -199 - 219 = \boxed{-418}$ .

2. $m = 438 - (-290) = 438 + 290 = \boxed{728}$ .

3. $128 - (-318) = 128 + 318 = \boxed{446}$ .

4. The sum of 429 and 429 is $429+429 = 858$ . We need to subtract this from 429, so $429 - 858 = \boxed{-429}$ .

5. The sum of 510 and 319 is $510+319 = 829$ . Subtracting -330, we get $829 - (-330) = 829 + 330 = \boxed{1159}$ .

6. Call the unknown number " $\star$ ". Then $\star + 298 = -398$ , so $\star = -398 - 298 = \boxed{-696}$ . (Think about it.)
