Answer:

The values of x and y to the given equations are x=-1 and
y=(10)/(3)

The solution is (-1,
(10)/(3))

Explanation:

Given equations are
x+3y=9\hfill (1)

and
3x-3y=-13\hfill (2)

to solve the given equations by elimination method :

Adding the given two equations (1) and (2) we get


x+3y=9


3x-3y=-13

_______________

4x=-4


x=-(4)/(4)

Therefore x=-1

Now substitute the value x=-1 in equation(1) we get

(-1)+3y=9

3y=9+1


y=(10)/(3)

Therefore the values of x and y to the given equations are x=-1 and
y=(10)/(3)

The solution is (-1,
(10)/(3))
