Question

i need someone to check this for me;;

4|v - 5| = 16

4v - 20 = 16
+20 +20
------------
4v = 36
/4 /4
------------
v = 9

4v - 20 = -16
+20 +20
------------
4v = 4
/4 /4
---------
v = 1

Answer 1

no don't use the distributive propetry

Answer 2

\[\pm (v-5) = 4\]

v - 5 = 4
v = 9

- v + 5 = 4
v = 1

Answer 3

why is there a + sign in front of (v - 5)

Answer 4

you have to get the numbers in the absolute value sign alone, you would do that by dividing 4 by 16, so then you'll have
|v - 5| = 4
Now what's NOT in the absolute value sign, you will turn into negative and positive to get your two soulitons
v -5= -4
add 5
v = 1
v-5=4
add 5
v=9

Answer 5

that means plus and minus
