Question

How do you solve |y−8|+6=15?

Answer 1

Answer:

Y = -1 and 17

Step-by-step explanation:

|y-8| + 6 = 15

|y-8| = 9

y-8 = ±9

Now taking the above two cases ono by one

1) y-8 = 9

y = 17

2) y-8 = -9

y = -1

The thing you must remember is whenever we open mode we have to take two cases

Like |x|=a

x = ±a
