Answer:
x=-1, y=9. (-1, 9).
Step-by-step explanation:
6x-y=-15
x+2y=17
--------------
y=6x-(-15)
y=6x+15
x+2(6x+15)=17
x+12x+30=17
13x=17-30
13x=-13
x=-13/13
x=-1
-1+2y=17
2y=17-(-1)
2y=17+1
2y=18
y=18/2
y=9
Answer:
n=radical of 28
Step-by-step explanation:
n^2=bc
n^2=28
n=radical of 28
X=4,,,,,,,,,,,,,,,,,,,,,,,,,,y=1,,,,,,,,,
Combine (5-i)+3i
-9(3z + 7)
distribute -9 to both 3z and 7
-27z - 63
-27z - 63 is your answer
hope this helps
