To solve, set your equation to your solution.

3x+1=19

Start by subtracting 1 from each side to start isolating the x.

3x+1=19
-1 -1
————-
3x=18

Next, divide both sides by 3 to completely isolate the x.

3x=18
—- ——
3 3

x=6

Therefore, x for f(x)= 19 is 6

You can check by inserting into the equation 3(6)+1=18+1=19.

Hope this helps!!

Answer:

Step-by-step explanation:

f(x) = 3x + 1

First, we substitute 19 for x :

f(x) = 3(19) + 1

Next we re write the problem and solve for 3 times 19 :

f(x) = 57 + 1

So, the answer should be :

f(x) = 58
