Answer:
We know that if
|
a
|
=
b
,
a
=
±
b
.
First, remove the absolute value. Since we do not know if
2
x
−
3
is positive or negative, we will need a
±
on the
7
:
|
2
x
−
3
|
=
7
⇒
2
x
−
3
=
±
7
Then, add
3
to both sides, and finally divide by
2
:
2
x
=
3
±
7
x
=
3
2
±
7
2
So
x
is equal to either
10
2
=
5
or
−
4
2
=
−
