Someone plzz help you get 10 points. Jason wants to solve the following system using the elimination method:

x + 3y = 10
2x + y = 5

What number should the equation 2x + y = 5 be multiplied by to eliminate y?

a. 2
b. -3
c. -2
d. 3

No single Correct answer. Both b and d will work

Step-by-step explanation:

You want to get rid of y.

The first equation has a 3 in front of the y

Therefore you would have to multiply the second equation by 3 or - 3

If you use -3 you would add the two equations

If you use 3 you would subtract the two equations.

It is either b or d. Both will give you the same answer.

- Three

  x + 3y =   10

-6x - 3y = - 15               Add

-5x = - 5                       Divide by - 5

x = -5/-5

x = 1

+ Three

x   + 3y =  10

6x + 3y = 15                   Subtract

-5x = - 5

x = -5/-5

x = 1                                Same thing.
