Answer:
B
Step-by-step explanation:
Lets start solving until we get stuck,
6|x|+25=15
Subtract 25 from both sides
6|x|+25-25=15-25
Subtract
6|x|=-10
Divide both sides by 6
6|x|/6=-10/6
Divide
|x|=-10/6
We get stuck here, we need x to be negative but we cant have a negative x since we have absolute value. This means the answer is b.
