Question

समीकरण को हल कीजिएx-2y=5,2x-4y=6​

Answer 1

Step-by-step explanation:

x-2 y=5 ..... equation(1)

2x-4y=6..... equation (2)

multipling equation (1) by2

2x-4y=10 ..... equation (3)

subtracting equation (3) and (2)

2x-4y= 10.....equation (3)

2x-4y=6........equation(2)

_______________

0x = 4

x=0/4

x=4

x=4put in equation (1)

x-2y=5

4-2y=5

2y= 5-4

2y=1

y=1/2

y= .5
