Question

If x-21 = 71-x , find the value of x​

Answer 1

Step-by-step explanation:

x-21=71-x

x+x =71+21

2x=92

x=92/2

x=46

Answer 2

Answer:

Hence, the value of x is 46.

Step-by-step explanation:

In context to questions asked,

We have to find the value of x,

Here we will use the transposition method.

It is given that,

$x-21 = 71-x$

Now rearrange the terms, we get

=> $x-21 = -x+71$

Add both sides by $21$, we get

=> $x-21+21 = -x+71+21$

=> $x= -x+71+21$

Add the numbers, we get

=> $x= -x+92$

Add both sides by $x$,

=> $x+x= -x+92+x$

=> $2x = 92$

Divide both sides by $2$,

=> $x = 46$
