Question

If 12 - 3b= 0, then find the value of b.

Answer 1

Solution Start :-

$=> 12 - 3b \: = 0 \\ \\ => - 3b \: = 0 - 12 \\ \\ => - 3b \: = - 12 \\ \\ => b \: = \frac{ - 12}{3} = > - 4 \\ \\ => \cancel { - }b \: = \cancel { - }4 \\ \\ => b \: = 4$

Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $12-3b=0.$

              To find:- Value of the expression.

              Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we will Identify the variables and constants.

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        By using the transposition method.

        we get,

                  $12-3b=0\\\\=>-3b=-12\\\\=>b=\frac{-12}{-3}\\\\=>b=4$

      Hence we will get the value $b=4.$
