Answer:
Step-by-step explanation:
it depends. if (for example) y=x2 then there are an infinite amount of answers. if there is an equation like: If (variable X)= (variable Y) + 5 and if X=5, what is Y? then there is only one answer. check an algebra book, it can give you a more detailed answer.
It does not matter what order it is in when using addition.
Answer:
The acceleration is

Step-by-step explanation:
Use the equation of motion,

where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.
We substitute the values into the equation and solve for the acceleration, a

This means that;

Divide both sides by 2 to get:
