it is 30 because 4x-3y to 12x-9y is 3 times bigger
So you can multiply 3 to 10, that will be 30!

Answer: The required value of the given expression is 30.

Step-by-step explanation: We are given that


4x-3y=10~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We are to find the value of the following expression :


12x-9y.

We have


12x-9y\\\\=3(4x-3y)\\\\=3*10~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{Using equation (i)}]\\\\=30.

Thus, the required value of the given expression is 30.
