Answer 1

➠Question:-

$\bullet \: \sf if \: \dfrac{9x}{2} = 3x + 3 \: then \: 3x - 2y = {?}$

➠Concept:-

In this question the concept of multiplication process of linear equation in two variables has been used for finding the required value of 3x-2y .We have found the solution by multiplication of number in linear equation.

➠Solution:-

We have,

$\sf :\longmapsto\dfrac{9x}{2} = 3x + 3$

Multiplying by 2 on both sides.

$\sf : \longmapsto \: 9x = 6x + 6$

$\sf : \longmapsto \: 9x - 6y = 6$

Now Dividing it by 3 on both side

$\sf : \longmapsto \: 3x - 2y = 2$

Hence, we got a result 2 at last.

Thus option (4) is correct.
