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

on simplification, we get



Step 2:-
and

on simplification, we get


dividing with 5 , we get

Final answer:-
The solution is
