Answer 2

Answer:

=> q = 2

Step-by-step explanation:

Given that:-

$18q - 3 = 15 + 9q$

To find:- The value of the expression:

Here we will use the transposition method.

First of all, we have to identify the variables and the constants.

Then solve the expression of both sides by using various mathematical operations.

As we have,

=> $18q - 3 = 15 + 9q$

We move all terms to the left:

=> $18q-3-(15+9q)=0$

=> $18q-(9q+15)-3=0$  

Simplifying it further, we get

=> $18q-9q-15-3=0$

=> $9q-18=0$

All terms containing q are moved to the left, while all other terms are moved to the right.

=> $9q=18$

Now, divide both sides by $9$:

=> $q = 2$

Hence, the required solution is 2.
