Determine if b = - 3 is a solution to 4b - 6 = - 18. Be sure to show all of your work.

Given b equals - 3, determine if it is a solution to 4b - 6 = - 18.

So, we have our given which is b = - 3, and we are asked to determine if it a solution to the above equation.

To do this, we can plug - 3 in for b and see if it works out.

Work:

Plug in - 3 for b.

4 (-3) - 6 = - 18

-12 - 6 = - 18

-12 - 6 = - 18

Thus, b = - 3 is a viable solution for the equation of 4b - 6 = - 18.
