Yes, you did it correctly.
We have two opposite quantities.
We have to show that opposite quantities combine to make zero.
What is a Vector quantity ? What are equal and opposite Vectors?
Any quantity with both magnitude and direction is called vector quantity.
Two vectors are said to be equal and opposite if they have same magnitude and angle of 180 degrees between them.
According to the question -
Assume a number line and mark a number say 'x' after 0 and a number
'-x' before zero. These two numbers represent the quantities with same magnitude. And it can be easily seen that the angle between line from center point 'O' to 'x' and the line from 'O' to '- x' is 180 degrees. Hence, these two equal and opposite quantities which will give a resultant value of = + x + (- x) = + x - x = 0
