See explanation.

Explanation:

The starting system can be written as:

{−8x+3y=713x−3y=−17

We can see that the coefficients of y are opposite numbers, so if we add both sides of the equations we get rid of one variable:

5x=−10⇒x=−2

Now if we substitute the calculated value of x to any of the equations we can calculate the remaining variable y:

−8⋅(−2)+3y=7

16−3y=7

−3y=−9⇒y=−3

Finally we can write that the solution is:

{x=−2y=−3
