Question

Is x=5,y=-2 a solution of the linear equation 3x-y=12​

Answer 1

Answer: No, it is not

Step-by-step explanation:

Replace x and y with the values given :-

= 3(5) - (-2) = 12

= 15 + 2 = 17

17 is not equal to 12

Answer 2

Answer:

Given Values :-

• x = 5
• y = -2

Linear Equation :-

• 3x - y = 12

Solution :-

• By putting the values of x and y, we get,
• 3(5) - (-2) = 12
• 15 + 2 = 12
• 17 = 12
• LHS ≠ RHS
• Hence, (5,-2) is not a solution of the linear equation 3x - y = 12.
