The system of equations we have is:

Step 1. substract the second equation from the first equation to eliminate variable x:

The minus sign changes the signs of the second equation, and now we have:

and the result of this is:
Step 2. From the result of the substraction -5y=14, solve for y:

Step 3. Substitute this value of y in the first original equation

To find the value of x.
We substitute y=-2.8

Step 4. Solve for x
