Question

Which equation has x=9 as a solution

Answer 1

All the Equations Have the solution

for ex. x + y = 9

where x = 9 , y = 0

Answer 2

Given,

x = 9

To find,

The equation that has x = 9.

Solution,

The equation that x = 9 as a solution will be (x-9) = 0.

We can easily solve this problem by following the given steps.

According to the question,

The solution of an equation is x = 9.

x-9 = 0 (Moving 9 from the right-hand side to the left-hand side result in the change of the sign from plus to minus.)

(Note that there can be more than one equation that has 9 as their solution. For example, we can add 5 on both sides of our equation. So, the second equation can be x-4 = 5.)

Hence, the equation that x = 9 as a solution is (x-9) = 0.
