The system of equations are:
2x − 4y = 6
−3x + 3y = 9
To eliminate x, you should:
1. multiply first equation with 3
2. multiply second equation with 2
3. add the new equations you got
So your answer is A.

Answer:
D. 
Step-by-step explanation:
We have been given that a bag contains x blue chips and y red chips. The probability of selecting a red chip at random is 3/7. We are asked to find the
.



Since we are told that probability of selecting a red chip at random is 3/7, so red balls are 3 and total balls are 7:

Since total balls are 7, so we will get:

Upon substituting
in expression
, we will get:

Therefore, the value of
is
and option D is the correct choice.
Answer:
24x^2
Step-by-step explanation:
