Question

3a - 4 = 2 (4 - a) ​

Answer 1

Answer:

18

Step-by-step explanation:

3a-4=2(4-a)

-1a=2(4-a)

a+a=8+1

2a=9

a=9/2

a=18

Answer 2

Answer:

=> $\frac{12}{5}$

Step-by-step explanation:

Given that:-

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

To find:- The value of the expression,

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

As we have,

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

Now rearrange the terms, we get

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

Distributing the terms, we get

=> $3a - 4 = -2 a+8$

Add both sides by $4$, we get

=> $3a - 4 +4= -2 a+8+4$

Simplifying it further, we get

=> $3a= -2 a+12$

Now, add both sides by $2a$, we get

=> $3a+2a= -2 a+12+2a$

=> $5a = 12$

Divide both sides by $5$,

=> $a = \frac{12}{5}$

Hence, the required solution is $\frac{12}{5}.$
