#### Answer:

See explanation.

#### Explanation:

The starting system can be written as:

#{(-8x+3y=7),(13x-3y=-17) :}#

We can see that the coefficients of

#5x=-10 => x=-2#

Now if we substitute the calculated value of

#-8*(-2)+3y=7#

#16-3y=7#

#-3y=-9 => y=-3#

Finally we can write that the solution is:
