Question

3x-y=5 & 2x-y=3 solve plz​

Answer 1

Step-by-step explanation:

we have

3x-y=5.......(1)

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

so subtracting eqn. 2 from 1 we get

3x-y=5

2x-y=3

(-). (+) (-)

_____________

x=2

putting the value of x in eqn. 1 we get

3(2)-y=5

y=1

so the values of x and y are 2 and 1 respectively.

Answer 2

Answer:

$3x - y = 5 \: \: eq(1)\\ 2x - y = 3 \: \: \: eq2 \\ (2) \\ using \: elemination \: method \: in \: eq(1) \: and \: (2) \\ 3x - y = 5 \\ 2x - y = 3 \\ x = 2 \\ put \: the \: value \: of \: x \: in \: eq(1) \\ 3 \times 2 - y = 5 \\ 6 - y = 5 \\ - y = - 1 \\ y = 1$
