2x + 3y = 6
5x + 2y = 4

which of the following equations could be the result of multiplication and addition to eliminate a variable in the system of equations?

19x = 24
19y = 22
11y = 22

Option c :11y = 22

Step-by-step explanation:

Given :

--(a)

 ---(b)

Solution :

First multiply equation (a) by 5 then it become :

--(c)

Then multiply equation (b) by 2 then it becomes :

--(d)

Now subtract (d) from (c)

⇒

⇒

⇒

⇒

Thus , option C is right.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
