Answer 1

Answer:

x =4

y =2

Step-by-step explanation:

it may be simple by eliminating method.

Answer 2

Answer:

The solution of pair of linear equations is x=4 and y=2.

Step-by-step explanation:

x-2y=0---------(1)

3x+4y=20-------(2)

Multiplying the Equation 1 by (2) we get:

2x-4y=0---------(3)

Adding equations 2 and 3 we get,

3x+4y+2x-4y=  20+0

⇒5x=20

⇒x=20/5

⇒x=4

Substituting the value of x in equation 1 we get,

⇒4-2y=0

⇒4=2y

⇒y=42

⇒y=2

Hence x=4 and y=2

The solution of pair of linear equations is x=4 and y=2.
