Question

3a-4=(4-a) value of a
​

Answer 1

Step-by-step explanation:

Answer

3a−4=2(4−a)

3a−4=8−2a

5a=12

a=2.4

Answer 2

Answer:

=> The value of a is 2.

Step-by-step explanation:

Given that:-

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

To find:- The value of the expression,

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

As we have,

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

Rearranging the terms, we get

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

Now add both sides by $4$,

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

Simplifying it further, we get

=> $3a = -a + 8$

Now add both sides by $a$,

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

=> $4a = 8$

Divide both sides by $4$,

=> $a = 2$

Hence, the required solution is 2.
