Answer 1

Answer:

x=1/3

Step-by-step explanation:

3x + 7= 8

3x= 8-7

3x= 1

x= 1/3

Answer 2

Answer:

=> The value of x is $\frac{1}{3} .$

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,

=> $3x+7=8$

Now subtract both sides by $7$, we get

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

Simplifying it further, we get

=> $3x=1$

Divide both sides by $3$, we get

=> $x = \frac{1}{3}$

Hence, the required solution is $\frac{1}{3} .$
