Answer:
A
Step-by-step explanation:
The additive inverse property states that if we have a number a, then:
Here, we have the equation:
And we divide both sides by 2:
To acquire:
So, we did <em>not</em> use the additive inverse property since we didn't add anything.
Instead, we used the<em> division property of equality</em> by dividing both sides by 2.
So, our answer is A.
And we're done!
For this case we must solve the following system of equations:
To solve we follow the steps below:
We multiply the second equation by -3:
Thus, we have the equivalent system:
We add the equations:
We look for the value of the variable "y":
Thus, the solution of the system is given by:
