Question

slove x+2y=5 and2x-y=0using any non-graphical method​

Answer 1

Answer:

x=1

y=2

Step-by-step explanation:

x+2y=5..............(1)

2x-y=0................(2)

equation  (2) can be written as

2x=y    or    y=2x

Substituting y=2x in 1st equation, we get

x+2(2x)=5

x+4x=5

5x=5

x=1

y=2x=2*1=2

THIS WAS SUBSTITUTION METHOD.
