Solve the equation 6 – 6x = 5x – 9x – 2.

The correct answer is: 4

• English

In the given question the equation is 6 – 6x = 5x – 9x – 2.
Here, we have to find the solution of the given linear equation in one variable.
Bring all the terms containing variables in one side by operating same numbers on both sides to balance the equation.
Step 1: Add 6x on both sides.
6-6x+6x= 5x- 9x-2+6x
6= 5x-9x-2+6x
Step 2: Add 2 on both sides.
6+2= 5x-9x-2+6x+2
6+2= 5x-9x+6x
8= 5x-9x+6x
Step 3: Solve the RHS.
8= 2x
Step 4: Divide both sides by 2.

So, the solution of the equation is 4.
Therefore, the correct option is a,i.e., 4.

Like terms are the terms having same variable of same power in which the coefficient may not be the same whereas unlike terms are the terms which don't have same variable. Addition and subtraction are possible in like terms but not in unlike terms.
