Answer:

x = -2

Step-by-step explanation:

hello :

the system is : 3x-5y=10 ...(*)

                       -x+3y=-6...(**)

multiply (**) by : 3   you have : -3x+9y = -18  ...(***)

add (*) and (***) : 4y= -8   so:  x = -2

3x-5y=10
-x+3y=-6 time (3)

3x-5y=10
-3x+9y=-18

4y=-8
4/4y=-8/4
y=-2
Now for x
y = -2
3x-5y=10
3x-5(-2)=10
3x+10=10
-10 -10
3x=0
3/3x=0/3
x = 0
