Answer:
( - 6 , 26 )
Explanation:
You can solve this in a number of ways, you can graph it, you can substitute the value of x into the first equation, or you can do it the elimination method.
So lets just do the substitution method because i can't do the others on here, i can't write :/.
so substitute x = -6 into the equation y = -3x + 8
y = -3(-6) + 8
y = 18 + 8
y = 26
now you know what (X) equals to and what (Y) equals to so its,
(-6,26)
