Answer: the answer is x= -2 , y=11
Step-by-step explanation:
First
1: we have to find the answer for x in x-y= -13
2: add y on both sides of the equation
3: we will get x= -13+y
Second
1: Substitute x in 3x-y= -17 with x=-13+y
2: then you will get 3(-13+y)-y= -17
3: multiply 3 with -13 and y
4: you will get -39+3y-y =-17
5: add 3y and -y
6: you will get -39+2y= -17
7: add 39 on both sides of the equation
8: you will get 2y=22
9: divide 2 on both sides
10: you will get y= 11
Third
1: plug 11 for y in x= -13+y
2: then you will get x= -13+11
3: you will x= -2
So x= -2 and y= 11
