8 = x

Answer 2

Answer:

=> The value of x is 8.

Step-by-step explanation:

Given that:-

$3x+7=5x-9$

To find:- The value of the expression:

Here we will use the transposition method.

As we have,

=> $3x+7=5x-9$

Now subtract both sides by $7$, we get

=> $3x+7-7=5x-9-7$

=> $3x=5x-9-7$

Subtract the numbers, we get

=> $3x=5x-16$

Subtract both sides by $5x$,

=> $3x-5x=5x-16-5x$

=> $-2x = -16$

Divide both sides by $-2$, we get

=> $x = 8$

Hence, the required solution is 8.
