Answer:
Step-by-step explanation:
x + 3 y = 1 ----------------(I)
-3x - 3y = -15 -------------(II)
Add the equations and y will be eliminated and we can find the value of x
(I) x + 3y = 1
(II) <u>-3x -3y = - 15</u> {Now add}
-2x = - 14
x = -14/-2
x = 7
Plugin x =7 in equation (I)
7 + 3y = 1
3y = 1 - 7
3y = -6
y = -6/3
y = -2
Answer:
I think the answers would be B and C.
Step-by-step explanation:
When you simplify 3^3 you get 27. Then your also going to simplify 8^3 and you’ll get 512. You’ll end up with 27/512.
So the answers that also equal to 27/512 is B and C. Hope this helps :))
