Question

Solve the absolute value equations below:

Answer 1

\[|x + 6|= 3\]

A) x = 3
B) x = 3, -3
C) x = -3, -9
D) x = 6, -6

Answer 2

This breaks into two equations:

\(x + 6 = 3\)

and

\(x - 6 = 3\)

-----------------

\(x+ 6 = 3\)

Subtract 6 to both sides:

\(x = -3\)

-----------------

\(x - 6 = 3\)

Add 6 to both sides:

What's 6 + 3? @pigglet

Answer 3

9

Answer 4

Yep, so the solutions are -3, and 9.

Answer 5

it would be -3,-9. there is no -3,9

Answer 6

The second equation is -x-6 not x-6 I believe.

Answer 7

As it is the negative form of (x+6)

Answer 8

Oh..that's right, my bad..I made the second equation wrong. So it should be (-3, -9).

'Cause you have to multiply -1 to both sides which gives you -9..

Answer 9
