Question

If f(x) = 3x - 1 and f(x) = 3f(x) = 3, find x.​

Answer 1

Answer:

x = 4/3

Step-by-step explanation:

f(x) = 3x - 1

f(x) = 3

set equal

3x - 1 = 3

add 1 to both sides

3x = 4

Divide both sides by 3

x = 4/3

Answer 2

Answer:

x=4/3

Step-by-step explanation:

$\tt f(x)=3x-1$  $[\tt f(x)=3]$

$\tt 3=3x-1$

$\tt 3+1=3x$

$\tt 4=3x$

$\tt x=\cfrac{4}{3}$
