Answer:
c) x=-5 , y=6
Step-by-step explanation:
To solve this questions we can use substitution!
1) Substitute x into the equation
x = -5
2 x -5 = -10
2) Substitute y into the equation
y = 6
3 x 6 = 18
3) Check the equation
From substituting both x and y into the equation we are left with -10 + 18 = 8
we can see that it matches and works out!!!
All the other options do not work with the question therefore can't be an answer, to check you can try each one out and see which one of them work
Hope this helps, have a great day!
