Answer :
We start with the equation
[tex]$$
3x + 16 = 7 + 2x.
$$[/tex]
Step 1: Subtract [tex]$2x$[/tex] from both sides.
Subtracting [tex]$2x$[/tex] from the left side and the right side gives:
[tex]$$
3x - 2x + 16 = 7 + 2x - 2x.
$$[/tex]
This simplifies to:
[tex]$$
x + 16 = 7.
$$[/tex]
Step 2: Subtract [tex]$16$[/tex] from both sides.
Subtracting [tex]$16$[/tex] from both sides to isolate [tex]$x$[/tex]:
[tex]$$
x + 16 - 16 = 7 - 16.
$$[/tex]
This simplifies to:
[tex]$$
x = -9.
$$[/tex]
Thus, the solution to the equation is
[tex]$$
x = -9.
$$[/tex]
[tex]$$
3x + 16 = 7 + 2x.
$$[/tex]
Step 1: Subtract [tex]$2x$[/tex] from both sides.
Subtracting [tex]$2x$[/tex] from the left side and the right side gives:
[tex]$$
3x - 2x + 16 = 7 + 2x - 2x.
$$[/tex]
This simplifies to:

$$[/tex]
Step 2: Subtract [tex]$16$[/tex] from both sides.
Subtracting [tex]$16$[/tex] from both sides to isolate [tex]$x$[/tex]:

$$[/tex]
This simplifies to:

$$[/tex]
Thus, the solution to the equation is
[tex]$$
x = -9.
