Question

Solve each of the following equation using the transportition method: 12 - b = 4b + 21 ​

Answer 1

Answer:

Step-by-step explanation:

12 - b = 4b +21

If - b goes in RHS it will become as + b

Similarly if +21 goes that side it will become as -21

⇒12-21 = 4b +b

⇒ 9 = 5b

⇒b = 5/9

Ans = b = 0.55

Hope this will help you

Answer 2

• We have to evaluate the given equation.

              Given data:- $12-b=4b+21.$

              To find:- Value of b.

              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,

                  $12-b=4b+21\\=>12=4b+b+21\\=>12=5b+21\\=>-5b=21-12\\=>-5b=9\\=>b=-\frac{9}{5}$

      Hence we will get the value $b=-\frac{9}{5} .$
