See explanation.

#### Explanation:

The system is:

#{(5x+y=5),(10x+3y=20):}#

If you multiply the first equation by

#{(-10x-2y=-10),(10x+3y=20):}#

If you add both equations you get:

#y=10#

Now you can substitute the calcukated value to the first equation to calculate the value of

#5x+10=5#

Answer:

The solution is:
