Question

If 2x -y-3=0 & 4x-y-5=0 then x=​

Answer 1

Answer:

x=1

Step-by-step explanation:

By elimination method

2x-y=3

4x-y=5

- + -

-2x = -2

x= 1

Answer 2

Answer:

x= 1

Step-by-step explanation:

2x-y-3=0

4x-y-5=0

now , 2x-y = 0+3

  2x-y = 3 - (1)

in the same way , 4x-y-5 =0

4x-y =5

now,

[2x-y = 3] 2

4x-2y=6 - (2)

subtract (1) from (2)

4x - 2y = 6

- 4x + y = -5  

_______

-y =1

y  = -1

now , put y = -1 in equ. (1)

2x -y =3

2x - (-1) = 3

2x+1 = 3

2x = 3-1

2x = 2

x=2/2

x=1
