Question

Solve and check whether your answer is correct or not for the following equation a 2x - 18 = 0

Answer 1

Answer:

9

Step-by-step explanation:

2x - 18 = 0

2x = 18

x = 18 / 2

x = 9

Ans.

Answer 2

Answer:

$\large\boxed{X=9}$

Step-by-step explanation:

To solve this problem, first you have to identify the solution of 2x-18=0. Then, you have to isolate it by the x on one side of the equation. Addition property of equality is adding from both sides of an equation same number from left to right and it doesn't change the equation at the same time.

Given:

2x-18=0

Solution:

First, you have to add 18 from both sides.

$\displaystyle 2x-18+18=0+18$

Solve.

Add the numbers from left to right.

$\displaystyle 0+18=18$

$\displaystyle 2x=18$

Now, divide by 2 from both sides.

$\displaystyle \frac{2x}{2}=\frac{18}{2}$

Solve.

Divide numbers from left to right.

$\displaystyle 18\div2=\boxed{9}$

$\large\boxed{X=9}$

Therefore, the solution of 2x-18=0 is x=9.

X=9, is the correct answer.
