Question

The solution of the given pair of the equation is 2x-y-3=0, 4x+y-3=0 * 2 points x=1, y= -1 x=1, y=1 x=3 , y= 2 x=2 , y= 2

Answer 1

Answer :

x = 1 , y = -1

(1st option)

Solution :

Here ,

The given equations are ;

2x - y - 3 = 0 -------(1)

4x + y - 3 = 0 -------(2)

We need to find the solution of the given pair of the equations .

Thus ,

Adding eq-(1) and (2) , we get ;

=> (2x - y - 3) + (4x + y - 3) = 0 + 0

=> 6x - 6 = 0

=> 6x = 6

=> x = 6/6

=> x = 1

Now ,

Putting x = 1 in eq-(2) , we have ;

=> 4x + y - 3 = 0

=> 4•1 + y - 3 = 0

=> 4 + y - 3 = 0

=> y + 1 = 0

=> y = -1

Hence ,

The required solution is :

x = 1 , y = -1

Answer 2

Answer:

⭐ Question ⭐

✏ The solution of the given pair of the equation is 2x-y-3=0 and 4x+y-3=0

⭐ To find ⭐

✏ We have to find the value of x and y

⭐ Solution ⭐

✏ 2x-y-3=0 -----(1)

✏ 4x+y-3=0 -----(2)

To eliminate x we multiply equation (1) by 4 and equation (2) by 2

8x-4y-12 = 0

8x+2y-6 = 0

(-) (-) (+)

-------------------------------------

6y - 6 = 0

y = -6/6

= -1

Putting y = -1 in the equation (1) we get,

2x-y-3 = 0

=> 2x-(-1)-3 = 0

=> 2x+1-3 = 0

=> 2x -2 = 0

=> 2x = 2

=> x = 2/2

=> x = 1

Hence, the value of x = 1 and

y = -1
