Question

3x = 2x + 18 solve and check​

Answer 1

$3x = 2x + 18 \\ 3x - 2x = 18 \\ x = 18$

Putting the value.

$3 \times 18 = 2 \times 18 + 18 \\ 54 = 36 + 18 \\ 54 = 54$

Answer 2

Answer:

=> x = 18

Step-by-step explanation:

Given that:-

$3x = 2x + 18$

To find:- The value of the expression:

Here we will use the transposition method.

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

Then solve the expression of both sides by using various mathematical

operations.

( i ) For solving:

As we have,

=> $3x = 2x + 18$

Subtract $2x$ from both sides, we get

=> $3x -2x= 2x + 18-2x$

Simplifying it further,

=> $x = 18$

( ii ) For checking

Now, put the value of x in the equation

=> $3x = 2x + 18$

=> $3(18)=2(18)+18$

=> $54=54$

Hence, the required solution is 18.
