Question

Solve the linear equation:3 ( b - 4 ) = 2 ( 4 - b )

Answer 1

Ello..✌✌

3 ( b - 4 ) = 2 ( 4 - b )

=> 3 b - 12 = 8 - 2 b

=> 3 b + 2 b - 12 - 8 = 0

=> 3 b + 2 b - 20 = 0

=> 5 b = 20

=> b = 20/5

=> b = 4

Answer 2

Answer:

=> The value of b is 4.

Step-by-step explanation:

Given that:-

$3 ( b - 4 ) = 2 ( 4 - b )$

To find:- The value of the expression,

To find the value of x, we must apply the transposition method:

As we have,

=> $3 ( b - 4 ) = 2 ( 4 - b )$

Rearranging the terms, we get

=> $3 ( b - 4 ) = 2 ( - b+4 )$

Now distributing the terms, we get

=> $3 b - 12= -2 b+8$

Add both sides by $12$, we get

=> $3 b - 12+12= -2 b+8+12$

=> $3b = -2b +20$

Add both sides by $2b$, we get

=> $3b +2b= -2b +20+2b$

=> $5b = 20$

Divide both sides by $5$,

=> $b = 4$

Hence, the required solution is 4.
