@Vocaloid

Answer 2

start by dividing both sides by -3

Answer 3

x+4 = =12?

Answer 4

nope, not quite

Answer 5

Answer 6

This is what i was given
x = 5 \3, x = −19\3
x = −3, x = −11
x = −3, x = 11
No solution

Answer 7

good, that gives us

|x + 7| = 4

now solve:

x + 7 = 4

AND

x + 7 = -4

you will get two x-values.

Answer 8

x = −3, x = 11?

Answer 9

-3 is right

11 is not

Answer 10

x + 7 = -4

x = ?

Answer 11

Would it be -11?

Answer 12

yup, so our answers are x = -3 and x = -11

Answer 13

I get how the one is -3 but don't understand how it is -11. Do you have time and mind explaining?

Answer 14

sure

x + 7 = -4

now we subtract 7 from each side

x + 7 - 7 = -4 - 7


x = -4 - 7 = -11

Answer 15
