Which system of equations represents the word problem?

Ox+y = 36 and y = 2 x
Oy= 2 x and 2 x - y = 36
02x+y = 36 and x - y = 36



Answer :

beicker

Answer:

12 and 24

Step-by-step explanation:

[tex]{ \tt{x = 2y - - - - (a)}} \\ { \tt{x + y = 36 - - - (b)}}[/tex]

Perform for eqn (b):

[tex]{ \tt{2y +y = 36}} \\ { \tt{3y = 36}} \\ { \tt{y = 12}}[/tex]

For x:

[tex]{ \tt{x = 2y}} \\ { \tt{x = 2 \times 12}} \\ { \tt{x = 24}}[/tex]
