Question

solve and check 2x-18=0​

Answer 1

Solution :

⇝ 2x - 18 = 0

⇝ 2x = 0 + 18

⇝ 2x = 18

⇝ x = 18/2

⇝ x = 9

Check :

Substituting x = 9, we get

⇝ 2x - 18 = 0

⇝ (2 × 9) - 18 = 0

⇝ 18 - 18 = 0

⇝ 0 = 0

Hence, LHS = RHS.

Answer 2

Answer:

=> The value of x is 9.

Step-by-step explanation:

Given that:-

$2x-18=0$

To find:- The value of the expression and also we have to verify it.

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,

=> $2x-18=0$

Now add both sides by $18$,

=> $2x-18+18=0+18$

=> $2x = 18$

Divide both sides by $2$,

=> $x = 9$

So, the value of x is 9.

Verification:-

Plug the value of x in the expression,

=> $2x-18=0$

=> 2 ( 9 ) - 18 = 0

=> 18 - 18 = 0

=> 0 = 0

LHS = RHS
