Answer:
6 should be subtracted from both sides of the equality.
Step-by-step explanation:
The subtraction property of equalities states that if we subtract a number at one side of the equality, we must also subtract the same number at the other side of the equality.
So, in this case, to isolate the variable, we have to subtract 6 from both sides of the equality as follows
[tex]6-2x=-3\\6-6-2x=-3-6\\-2x=-9[/tex]
AS you can see, by doing that, we have the variable almost isolated.
Therefore, the answer is 6.
Additionally, is we want to find the solution of the equation, we need to divide each side of the equation by -2
[tex]\frac{-2x}{-2}=\frac{-9}{-2}\\ x=\frac{9}{2}[/tex]
