Question

|3u-18|=0

A. 6
B. 9
C. {-6, 6}
D. {6, 9}

Answer 1

you can automatically eliminate options C and D since you know that the answer has to be a single number, not a range of values.

Now, you are left with A or B. let's solve to figure out:\[|3u-18|=0\]\[3u-18=0\]\[3u=18\]\[u=\underline{~~~~}?\]
