which number is a the solution of the equation [5x-2] = 8?
a.}6/5
b.}1/2
c.}negative 6/5
d.}negative 1

Is this [5x - 2] supposed to represent absolute value of 5x - 2 ? If so, set up two equations:

5x - 2 = 8

and

5x - 2 = -8

Solve each and see if one of the solutions is included in your selection of answers.

I hope this will help.
