Solution

The correct option is B 12
Given, x+147=12×6+13x
We need to solve x by isolating it on one side of the equation.

Step 1 : Collect all variable terms on one side of the equation.
x+147=12×6+13x

So, subtract x on both sides of the equation
xx+147=3+13xx
147=3+12x

Step 2: Collect constant terms on other side of the equation by subtracting 3 from both the sides.
1473=33+12x12x=144

Step 3: Make the coefficient of the variable term equal to 1 by dividing from 12 on both the sides.
12x12=14412x=12

Hence, x=12
