Full solution

Q. What value of

x

is a solution to this equation?

\newline

3x = 9

\newline

Choices:

\newline

(A)

x = 3

\newline

(B)

x = 4

Isolate x: Isolate the variable $x$ . $\newline$ $3x = 9$ $\newline$ Divide both sides by $3$ to solve for $x$ . $\newline$ $(3x) / 3 = 9 / 3$ $\newline$ $x = 9/3$
Calculate $x$ : Calculate the value of $x$ . $x = \frac{9}{3}$ $x = 3$
Check answer choices: Check the answer choices. $\newline$ The value of $x$ is $3$ . $\newline$ So, $x = 3$ is the correct answer choice;
