Question

Solve for r: |5r - 18| = 0. Show your work.

Answer 1

answer or process?

Answer 2

Well, both if you can.

Answer 3

sure, look at it this way:
the absolute value sign is meaningless, because if
|a|=0 then a=0
that is the only way
so you just need to solve
5r-18=0

Answer 4

So would that be 3.6 or {3.6, -3.6}?

Answer 5

5r-18=0
5r=18
r=18/5=3.6
since we dropped the absolute value signs there is no negative answer, just the one:
3.6

Answer 6

Ok thanks
