Answer:
<h3>Add to eliminate y.</h3>
Step-by-step explanation:
Given the equations
-9x + y = 71.... 1
-x - y = -1 .... 2
Using elimination method we can eliminate y first since they have the same coefficient.
To do that we will need to add up both equations. We are adding because the coefficient of y in both equations has different signs. If they have the same sign, we would have subtracted.
<em>Hence the correct option in this case is to add to eliminate y.</em>

Answer:
1 ÷ 11
Step-by-step explanation:
The computation is shown below:
let us assume the yellow cubes be x
So, blue cubes be 2x
And, green cubes be 2x (4) 8x
Now the ratio is
Yellow: Blue: green
x:2x:8x
1:2:8
Now the probability of yellow cubes is
= 1 ÷ (1 + 2 + 8)
= 1 ÷ 11
