put this solution on YOUR website!Hi, Hope I can help,
.
Solve
.
Absolute value will always make the numbers inside positive, absolute value is the distance away from "0" on the number line
.
|5| = 5, it is 5 units away from zero
.
|-5| = 5, it is also 5 units away from zero
.
, to get rid of the absolute value signs, we can say the left side equals 10, as well as (-10), since the absolute will make it positive, so we really have two equations
.
, and
, now let us solve for "x"
.
First equation,
.
We need to move (-4) to the right side
.
=
=
, to find "x" we need to divide each side by "7"
.
=
=
, we can check by replacing "x" with "2" in the equation
.
=
=
=
(True)
.
Now let us solve the second equation,
.
We need to move (-4) to the right side
.
=
=
, to find "x" we will divide each side by "7"
.
=
=
, we can check by replacing "x" with (
)
.
=
=
=
(True)
.
Your two answers are (
), and (
)
.
If we replaced these two numbers into the original equation, they should work
.
replace with "2",
=
=
=
=
( absolute value means that it is "10" units from "0" )
.
replace with (
),
=
=
=
=
( True ) ( Remember, the absolute signs will make any number positive, absolute value is just how far the number is from "0", (-10) is 10 units from "0"
.
Your two answers are
