Question

solve which of the following equation 3x+y=9
option
(a) (4,2) (B) (3,0) (c) (2,0) (d) (none)​

Answer 1

Option B, (3,0)

Why? Because when you substitute the values of x and y, LHS and RHS becomes equal.

LHS: 3x + y

Taking option B, where x = 3, y = 0

--> 3(3) + 0 = 9

RHS = 9

∴ LHS = RHS

So, option B is the right one.
