Question

|3x+12|=18 The solution to this equation is 2.
Answer
a.True
b.False

Answer 1

It seems like there should be another answer as well since there are 2 numbers that are exactly 18 units from 0.
What do you think?

Answer 2

false?

Answer 3

I think so.

Answer 4

\[|3x+12|=18\]
\[3x+12=\pm18\]
The equations splits off here in two parts, 3x+12=18 and 3x+12=-18
This means you MUST have two solutions unless you can eliminate one based on conditions (i.e.: the answer has to be positive)

They didn't give you conditions, so you have more than one answer. False. :-)

Answer 5

By the way, can you find what the other answer is for that equation? ;-)
