Question

x+y=8 , 2x+y= 13 solve by elimination method​

Answer 1

Answer:

xy=8

xy=13/2

Step-by-step explanation:

1 st answer is

x+y=8

xy=8

2nd answer is

2x+y=13

xy=13/2

here is your solution

Answer 2

x = 5 and y =3

Given

[tex]x+y=8\\ 2x+y=13[/tex]

To Find

Solve x and y using elimination method

Solution

To solve by elimination method, we can add or subtract the two equations from each other. In this example, lets subtract the two equations. That is,

$(2x+y) - (x+y) = 13 -8$

$x = 5$

Substituting for $x$ in equation $x+y =8$ we get

[tex]5+y=8\\ \\ y = 3[/tex]

Hence, x = 5 and y = 3
