Question

Solve : 7x-4 = 3x + 8​

Answer 1

Answer:

-4 -8 = 3x -7x

solve

4 + 8 = 3x-7x

12=4x

x = 4/12

so x = 3

Step-by-step explanation:

first transfer x to x and simple number to number

so it will be - 4 -8 = 3x-7x

so then it will be 4+8 because - - = + so 4+ 8

8 became negative because we transfered it to lhs

3x - 7 -7 because of transpose

after doing sum and sub we have 4 and 12

so we cannot sum x and simple number so we simplify and we get 3

Answer 2

To find : value of $x$  

Given : $7x -4 = 3x + 8$

Solution :

• Here, we will use the below following steps to find a solution using the transposition method:

1. We will Identify the variables and constants in the given equation.
2. Then we differentiate the equation as LHS and RHS.
3. We take constants at RHS leaving variable at LHS.  
4. Simplify the equation using arithmetic operation as required to find the value of $x$ .
5. Then the result will be the solution for the given linear equation. By using the transposition method. we get,

• $7x -4 = 3x + 8$

         $7x-3x = 8 +4 \\4x = 12 \\x = 3$

Hence, value of $x$ is  $3$ .
