Question

How do you know whether the given value is a solution of the equation: 4x-9(6-5w)=44, w=3?

Answer 1

`-81 = 44` is not true therefore `w = 3` is not a solution to this equation.

Explanation:

Substitute `3` for every occurrence of `w` and determine if each side of the equation is equal:

`9(6 - (5*3)) = 44`

`9(6 - 15) = 44`

`9(-9) = 44`

`-81 = 44`
