Question

The solution set of |R - 3| = 10 is

{7, 13}
{-7, 13}
{-13, 13}

Answer 1

hi magan,
use the property of absolute sign that
|x|=y gives
x=y or x=-y
so, what do u get for
|R-3|=10 ?

Answer 2

sorry still dont get it

Answer 3

we break up one equation of the form
|x| = -y
as
x=y or x=-y

in words, right side = left side, or right side = - left side

similarly break up |R-3| = 10
in 2 simple equations.
you can do it!

Answer 4

|R-3| = 10
So what you need to do is to find values that will make R-3 be equal to 10 and be equal to negative 10, right?
Hence R-3 = 10 --> R=?
R-3 = -10 --R=?

Answer 5

If you got the 2 Rs there, that's already the solution. Get it @magan ?
