Question

solve 5 Ix-5I = 25

Answer 1

|x-5|=25/5
or |x-5|=5
hence x-5=5 or x-5=-5
thus x=10 or x=0

Answer 2

thanks

Answer 3

welcome dear

Answer 4

i have another question something similar to it. its I3xIgreater than or equal to 15 . i would have to switch the sign correct since my other answer will be a negative?

Answer 5

It will go the same way as the previous problem. First step is to make sure the absolute value is isolated (in this problem, it starts out that way). Then we show it as two inequalities\[\left| 3x \right| \ge 15 \implies 3x \ge 15~~ or~~3x \le -15\]

Answer 6

You can easily solve those to get\[x \ge 5~~or~~x \le -5\]
