Answer:
can bcz triangle has 3 sides here 3 cm are there
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!!
