Answer:
The Right option is D
Explanation:
From the picture below,
For A,
15y = 6x
Where we divide both side of the equation by 3
15y/3 = 6x/3
5y = 2x
For B,
y = 2/5(x)
y×5 = 2x
5y = 2x.
For C,
10y = 4x
Divide both side of the equation by 2
10y/2 = 4x/2
5y = 2x.
For D,
5xy = 2. It can not be simplified futher.
Therefore,
From the above simplification, We can see that,
Equation A = Equation B = Equation C.
Equation D is the only Equation that does not belong to the other three.
Hence the right option is D
