Question

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

Answer 1

x=4/3

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}`

Answer 2

x = 4/3

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
