Question

check whether x = 2 &y= -2 is a solution of 2x - y = 6 ​

Answer 1

Answer:

Given :

x = 2 & y = -2

Solution :

Putting the value of x and y in the polynomial :

$2x - y = 6$

$2(2) - ( - 2) = 6$

$4 + 2 = 6$

$6 = 6$

Both the sides (LHS and RHS) are equal. So, x = 2, y = -2 is a solution of 2x - y = 6

Ans. Yes, x = 2, y = -2 is a solution of 2x - y = 6

Hope it helps.

Answer 2

Answer:

x = 2 & y = -2

Step-by-step explanation:

Putting the value of x and y in the polynomial :

2x - y = 62x−y=6

2(2) - ( - 2) = 62(2)−(−2)=6

4 + 2 = 64+2=6

6 = 66=6

Both the sides (LHS and RHS) are equal. So, x = 2, y = -2 is a solution of 2x - y = 6

Ans. Yes, x = 2, y = -2 is a solution of 2x - y = 6
