Best answer
Correct answer is (a) x=2, y=2

The best I can explain: To find the solution of given equation, put the respective values of x and y in the given equation. If it satisfies the equation, it is the solution of given equation.

Let’s check the values given in option a, which are x=2,y=2.

2(2) + 4(2) = 4 + 8 = 12

Which satisfies the equation 2x+4y=12

Hence, it is the solution of the given equation.
