Question

Given f(x) = 3x – 1, solve for x when f(x) = -7.

Answer 1

Answer:

x = -2

Step-by-step explanation:

Given f(x) = 3x – 1

f(x) = -7

3x-1 = -7

3x = -7+1

3x = -6

x = -2

Answer 2

Answer:

x = -22

Step-by-step explanation:

given:

$f(x) = 3x - 1$

solve for x, when:

$f(x) = -7$

replace x with -7

~~~~~~~~~~~~

➡️ $x = 3(-7) - 1$

➡️ $x = -21 - 1$

➡️ $x = -22$
