# Does x satisfy the equation?

A number is a solution to an equation if plugging it in results in a true statement.

Is v = 5 a solution to the equation ?

yes

no

Solution:

Plug v = 5 into the equation and simplify.

 ? =
1 Plug in v = 5

1
 ? =
1 Divide

 Yes, 1 = 1 .

So, v = 5 is a solution to the equation .
