For each value of u, determine whether it is a solution to - 15 = 1 - 4u

u

2 - is it a solution?

-9 is it a solution?

-6 is it a solution?

4 is it a solution?

1. No

2. No

3. No

4. Yes

Step-by-step explanation:

Plug each option into u then solve the equation and see if the answer matches - 15.

Ex. - 15 = 1 - 4 (2)

-15 = 1 - 8

-15 = - 7

-15 does not equal - 7 therefore it is false. Use Pemdas to solve.
