Solve for [tex]x[/tex]:

[tex]7 + 4x = 16 + x[/tex]

Options:
A. [tex]x = 4 \frac{3}{5}[/tex]
B. [tex]x = 3[/tex]
C. [tex]x = 1 \frac{4}{5}[/tex]
D. [tex]x = 7 \frac{2}{3}[/tex]

Answer :

To solve the equation [tex]\(7 + 4x = 16 + x\)[/tex] for [tex]\(x\)[/tex], we’re going to follow these steps:

1. Get all the [tex]\(x\)[/tex] terms on one side of the equation and the constant terms on the other.
Start by subtracting [tex]\(x\)[/tex] from both sides of the equation to get all the variable terms on one side:
[tex]\[
7 + 4x - x = 16
\][/tex]

Simplify:
[tex]\[
7 + 3x = 16
\][/tex]

2. Isolate the term with [tex]\(x\)[/tex].
Subtract 7 from both sides to move the constant to the other side:
[tex]\[
3x = 16 - 7
\][/tex]

Simplify:
[tex]\[
3x = 9
\][/tex]

3. Solve for [tex]\(x\)[/tex].
Divide both sides by 3 to solve for [tex]\(x\)[/tex]:
[tex]\[
x = \frac{9}{3}
\][/tex]

Simplify:
[tex]\[
x = 3
\][/tex]

So, the solution to the equation [tex]\(7 + 4x = 16 + x\)[/tex] is [tex]\(x = 3\)[/tex].
