Question

chek weather the values satisfy the given experience and write how 2x=18,where x is 7​

Answer 1

Answer:

If 2x = 18 then x = 9 and x = 7 does not satisfy the given experience.

Step-by-step explanation:

$2x = 18\\ x=\frac{18}{2} \\ x=9$

The value of x is 9

now check x = 7.

$2x = 2(7) = 14 \neq 18$

So, x = 7 does not satisfy the given experience.

Answer 2

Answer:

Step-by-step explanation:

2x = 18 ⇒ x = 18/2 ⇒ x = 9

Now substituting " x = 2" in the given equation,

2x = 2 × 7 = 14

∴ The given is not satisfied where x = 2 .
