Final Thoughts

To isolate 14x, add 27 to both sides of the equation to eliminate the constant term on the left:

14x - 27 + 27 = 16 + 27

Simplify:
14x = 43

Step 2: Solve for x

Now divide both sides by 14 to solve for x:

x = 43 ÷ 14

So:

x = 43/14 (this is an exact fraction)
or approximately x ≈ 3.07 (decimal form)
