Question

The option which is a solution of the equation 2x+3y=6 is:- options_a.(1,2) b.(1,1) c.(-3,4) d.(-3/2)​

Answer 1

Answer:

Option [c](-3,4) is the correct answer

Step-by-step explanation:

substituting option (a) 1,2

⇒2(1) + 3(2) = 6

2+6 =6

8 ≠ 6                               ∴ 1,2 is not a solution

substituting option (b) 1,1

⇒2(1) + 3(1) = 6

2 + 3 = 6

5 ≠ 6                               ∴ 1,1 is not a solution

substituting option (c) -3,4

⇒2(-3) + 3(4) = 6

-6 + 12 = 6

6 = 6                               ∴ -3,4 is a solution

substituting option (d)-3,2

⇒2(-3) + 3(2) = 6

-6 + 6 = 6

0  ≠ 6                               ∴ -3,2 is not a solution
