------------------------------------------------ Which equation can be used to solve for [tex]x[/tex]?

A. [tex]30x = 145[/tex]
B. [tex]27x = 145[/tex]
C. [tex]5x + 25 = 145[/tex]
D. [tex]2x + 25 = 145[/tex]

Solve for [tex]x[/tex].

Answer :

To solve for [tex]\( x \)[/tex], let's start by identifying the correct equation. The equation we should use is:

[tex]\[ 5x + 25 = 145 \][/tex]

Now, follow these steps to solve for [tex]\( x \)[/tex]:

1. Subtract 25 from both sides:

This helps to isolate the term with [tex]\( x \)[/tex] on one side of the equation.

[tex]\[
5x + 25 - 25 = 145 - 25
\][/tex]

Simplifying this, we get:

[tex]\[
5x = 120
\][/tex]

2. Divide both sides by 5:

This will solve for [tex]\( x \)[/tex] by isolating it completely.

[tex]\[
x = \frac{120}{5}
\][/tex]

Calculating this gives:

[tex]\[
x = 24
\][/tex]

Thus, the solution for [tex]\( x \)[/tex] is 24.
