Question

The pair of equations x+2y-5=0 and -4x-8y+20=0 have

Answer 1

Answer:

The same value of X................

Answer 2

EXPLANATION.

equation are =

=> x + 2y - 5 = 0

=> -4x - 8y + 20 = 0

To find value of x and y.

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

=> - ( 4x + 8y - 20 ) = 0

=> 4x + 8y = 20 ......(2)

From equation (1) and (2) we get,

=> multiply equation (1) by 4

=> multiply equation (2) by 1

we get,

=> 4x + 8y = 20

=> 4x + 8y = 20

We get,

value of x = 0 and y = 0
