Answer 2

Answer:

=> The value of x is -1.

Step-by-step explanation:

Given that:-

$3x +10 =7$

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,

=> $3x +10 =7$

Subtract both sides by $10$, we get

=> $3x +10 -10=7-10$

Simplifying it further, we get

=> $3x = -3$

Divide both sides by $3$, we get

=> $x = -1$

Hence, the required solution is -1.
