A. {2/3, 2}
B. {2, 3}
C. {2, 5}
D. {1/3, 2} Solve |2y - 2| = y.
A. {2/3, 2}
B. {2, 3}
C. {2, 5}
D. {1/3, 2} @Mathematics

Answer 1

2y-2=y and 2y-2=-y
2y=y+2 and 2y=2-y
y=2 and y=2/3

Answer 2

so A

Answer 3

Okay thank you

Answer 4

do you understand how I got that?

Answer 5

No not really

Answer 6

ok well this is how you do it

abs(whatever)= something
this means that
(whatever)=soemthign and (whatever)=negative something

so forexample

abs(x)=3 means x=3 and x=-3

also if it said

abs(x) + 2=3, this means you have to isolate the absolute to just itself so it would be
abs(x)=1 [subtract the 2]


Does that help?

Answer 7

Um yea actually it does.

Answer 8
