Answer 1

Answer:

-5

Step-by-step explanation:

2x-5=7x+20

Transposing,

2x-7x=20+5

-5x=25

x= -5

Answer 2

Answer:

The value of the equation will be -5.

Step-by-step explanation:

According to the data given in the question,

We have to find the value of the equation,

Given that,

$2x-5=7x+20$

Here we will use the transposition method,

Now, adding both sides by 5:

=> $2x-5+5=7x+20+5$

Simplifying it further, we get

=> $2x=7x+20+5$

Add the numbers,

=> $2x=7x+25$

Now, subtract both sides by $7x$:

=> $2x-7x=7x+25-7x$

=> $-5x = 25$

Divide both sides by -5,

=> $x = -5$

Hence, the required solution is -5.
