Question

Hindi given pair of linear equation X + 2 Y is equal to 4 and 4 x minus 2 Y is equal to 6 find the value of x​

Answer 1

Answer:

=>x+2y=4

=> x = 4 - 2y .....i

Now, 4x - 2y = 6

4(4-2y) -2y = 6 from i

16 - 8y - 2y = 6

-10y = -10

y = 1

from i

x = 4 - 2y

= 4 - 2

= 2

so the value of x is 2

Answer 2

The value of x is 2.

Step-by-step explanation:

We have,

$x+2y=4$ ......(1)

and

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

Taking 2 common from equation (2), we have :

$2x-y=3$ .....(3)

Multiply equation (1) by 2, we get :

$2x+4y=8$ ......(4)

Subtracting equation (1) and (2) we get :

$2x-y-(2x+4y)=3-8\\\\-5y=-5\\\\y=1$

Put y in equation (1), we get :

$x+2(1)=4\\\\x=2$

So, the value of x is 2.
