3x=8-7

3x=1

x=1/3

it is the correct answer

Answer 2

Answer:

=> The value of x is 5.

Step-by-step explanation:

Given that:-

$3x - 7 =8$

To find:- The value of the expression:

Here we will use the transposition method.

We have to follow these steps:-

( i ) First of all, we have to identify the variables and the constants.

( ii ) Get the variable to one side of the equation. Maintain equation balance while calculating.

( iii ) Then solve the expression of both sides by using various mathematical operations. Simplify both sides.

As we have,

=> $3x - 7 =8$

Add both sides by $7$, we get

=> $3x - 7 +7=8+7$

Simplifying it further, we get

=> $3x = 15$

Divide both sides by $3$,

=> $x = 5$

Hence, the required solution is 5.
