Question

How do I find the absolute value of |2y-9|=1
​

Answer 1

1) rearrange the absolute value inequality l2y-9l>1
2)clear the absolute value bars
3) solve the negative case
4)solve the positive case
5) wrap up the solution

Answer 2

y=4,5

Explanation:

Anything inside an absolute value will become postive.

So, 2y-9 can be -1 because the absolute value of -1 is 1.

Knowing this,

2y-9 = 1

or

2y-9 = -1

2y-9=1

2y=10

y=5

and

2y-9=-1

2y=8

y=4

y=4,5
