Answer:
.
Step-by-step explanation:
Note: The number is not in proper form. Consider the given number is 
.
If a number is added to another number and we get zero, then the added number is known as additive inverse.
Let a be a number, then
So, -a is the additive inverse of a. It means, additive inverse is the same number with opposite sign.
Consider the given number is .
Therefore, the additive inverse of is .
D. x > 5
Combine like terms. 3x - x = 2x and 3 - 7 = -4. The equation is now 2x - 4 > 6. Now add 4 to both sides. 2x > 10. Now divide by 2 to get 'x' alone, leaving you with x > 5
