Answer:
y = -2 and y= 6
Step-by-step 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 [tex]10-5 y= 20[/tex]
on simplification, we get [tex]10-20 =5 y[/tex]
[tex]-10 = 5 y[/tex]
[tex]y=-2[/tex]
Step 2:-
and [tex]10-5 y= - 20[/tex]
on simplification, we get [tex]10+20 =5 y[/tex]
[tex]30 = 5 y[/tex]
dividing with 5 , we get
[tex]y=6[/tex]
Final answer:-
The solution is
[tex]y=-2[/tex]
[tex]y=6[/tex]
