Question

graph of pair of equations x-y+2=0 and 4x-y-4=0

Answer 1

Answer:

x = 2  and  y = 4.

Step-by-step explanation:

Given :

x - y + 2 = 0

y = x + 2 ... ( i )

4 x - y - 4 = 0

y = 4 x - 4  ... ( ii )

From ( i )  and  ( ii )  we have

x + 2 = 4 x - 4

4 x - x = 2 + 4

3 x = 6

x = 2

Now put x = 2 in ( i )

y = x + 2

y = 2 + 2

y = 4

So we get x = 2  and  y = 4.

Now see the graph there is intersection point ( 2 , 4 ) which show that

values of x and y is correct.

Thus we get answer.

Answer 2

Answer:

x = 2 and y = 4

Step-by-step explanation:

Given:

x - y + 2 = 0

y = x + 2 ... ( i )

4 x - y - 4 = 0

y = 4 x - 4 ... ( ii )

From ( i ) and ( ii ) we have

x + 2 = 4 x - 4

4 x - x = 2 + 4

3 x = 6

x = 2

Now, put x = 2 in ( i )

y = x + 2

y = 2 + 2

y = 4

So, we get x = 2 and y = 4.

Now, see the graph there in intersection point ( 2 , 4 ) which show that values of x and y is correct.
