Question

If g(x) = 3x - 1 and if g(x) = 7, then which of the following is the value of x?

A.) 8/3

B.) 21

C.) 20

D.) 9 3​

Answer 1

Given :

• g(x) = 3x - 1
• g(x) = 7

To Find :

• Value of x = ?

$\\ \qquad{\rule{200pt}{2pt}}$

SolutioN :

$\dag$ Calculating the Value of x :

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { g(x) = 3x - 1 = g(x) = 7 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { g(x) = 3x = g(x) = 7 + 1 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { 3x = 8 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; {\underline{\boxed{\orange{\pmb{\frak { x = \dfrac{8}{3} }}}}}} \; \bigstar \\ \\ \\ \end{gathered}$

$\therefore \;$ Value of x is 8/3 .

$\\ \qquad{\rule{200pt}{2pt}}$

Answer 2

Answer:

its answer is option (A)

Step-by-step explanation:

g(x) = 3x-1 = g(x) = 7

g(x) = 3x = g(x) = 7+1

g(x) =3x = g(x) = 8

g(x) =x = 8/3

ANSWER IS 8/3
