Question

BRUH SOMEONE HELP ME also explain:)

Answer 1

Answer:

$x=7$

Step-by-step explanation:

So we have the function:

$w(x)=3x-7$

And we want to find x when w(x) is 14.

So, substitute 14 for w(x):

$14=3x-7$

Add 7 to both sides. The right cancels:

$21=3x$

Divide both sides by 3:

$x=7$

So, the value of x is 7.

The correct answer is the first option.
