Question

x+2x = 18. solve for x.

Answer 1

x+2x = 18

=> 3x = 18

=> x = 6

Hence , x=6

Answer 2

Answer:

=> The value of x is 6.

Step-by-step explanation:

Given that:-

$x+2x = 18$

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,

=> $x+2x = 18$

Combining the like terms, we get

=> $3x = 18$

Divide both sides by $3$,

=> $x = 6$

Hence, the required solution is 6.
