Question

solve 2x-y =3and 4x+y=3 By any method

Answer 1

Step-by-step explanation:

2x-y=3

4x+y=3

here applying elimination method.

y is eliminated.

6x=6

x=6/6

x=1

substitute x=1 in 2x-y=3.

2(1)-y=3

2-y=3

-y=3-2

-y=1

y=-1

Answer 2

Answer:

x = 1, y = -1

Step-by-step explanation:

Using elimination method.

Simply add the given equations.

2x - y = 3   ----- equation 1

4x + y = 3  ------ equation 2

 -------------------

6x = 6

x = 1

Substituting the value of x in equation 1,

2  (1) -y = 3

2 - y = 3

- y = 3 - 2

- y = 1

y = -1
