Question

If 2a-5=a+2, then which of the following is the value of a? (a) 4 (b) 2 (c) 5 (d) 7​

Answer 1

Answer:

=> The option ( d ) is the correct answer.

Step-by-step explanation:

Given that:-

$2a-5=a+2$

To find:- The value of a,

For solving this, we have to use the transposition method:  

As we have,

=> $2a-5=a+2$

Add both sides by $5$, we get

=> $2a-5+5=a+2+5$

Simplifying it further, we get

=> $2a=a+2+5$

Add the numbers, we get

=> $2a=a+7$

Now, subtract both sides by $a$,

=> $2a-a=a+7-a$

=> $a = 7$

Hence, the required solution is 7.
