Question

slove by elimination method x+2y=5 2x+y=5​

Answer 1

Answer:

x=5/3,Y=5/3.

Step-by-step explanation:

both x and y will be the same

Answer 2

Answer:

x+2y=5 - - - - - equation 1

2x+y=5- - - - - - equation 2

Multiply equation 2 with number 2

So we get 4x+2y=10- - - - - equation3

By elimination method, take equation 2&3

Subtract eq3 from eq1

x+2y=5

4x+2y=10

(-) (-) (-)

________ eliminate 2y on both eq

- 3x=-5

x=5/3

Substitute x on eq 1

5/3+2y=5

5+6y/3=5

5+6y=15

6y=10

y=10/6

y=5/3
