Answer 2

Answer:

=> The value of x is -15.

Step-by-step explanation:

Given that:-

$2x - 10 = 4x +20$

To find:- The value of the expression,

To solve this expression, we have to use the transposition method:  

As we have,

=> $2x - 10 = 4x +20$

Add both sides by $10$, we get

=> $2x - 10 +10= 4x +20+10$

Simplifying it further, we get

=> $2x = 4x +20+10$

Add the numbers, we get

=> $2x = 4x +30$

Subtract both sides by $4x$, we get

=> $2x -4x= 4x +30-4x$

=> $-2x = 30$

Divide both sides by $-2$,

=> $x = -15$

Hence, the required solution is -15.
