Answer:

y = -2 and y= 6

Explanation:

Step 1:-

Given solution is |10-5 y|=20

we know that modulus |x| = 1

we will take values x= -1 and x=1 so we will apply like this on above given problem is
10-5 y= 20

on simplification, we get
10-20 =5 y

-10 = 5 y

y=-2

Step 2:-

and
10-5 y= - 20

on simplification, we get
10+20 =5 y

30 = 5 y

dividing with 5 , we get

y=6

Final answer:-

The solution is

y=-2

y=6
