Key Insights

How to Solve for $ z $ in the Equation

Start by expanding the left-hand side: $ 3(z + 4) - 2 = 3z + 12 - 2 = 3z + 10 $.
The equation now reads:
$ 3z + 10 = 5z + 1 $.

Next, move all $ z $-terms to one side by subtracting $ 3z $ from both sides:
$ 10 = 2z + 1 $.

Then subtract 1 from both sides:
$ 9 = 2z $.

Finally, divide by 2:
$ z = \frac{9}{2} $ or $ z = 4.5 $.

Final Thoughts

This clear, logical flow makes the process accessible and reinforces fundamental algebra—skills increasingly relevant in STEM education and everyday decision making.

Common Questions About the Equation

Q: Why do the brackets matter in the equation?
Brackets ensure the expression $ z + 4 $ is calculated first, preserving the intended order of operations. This helps maintain clarity in equations where multiple operations interact.

Q: Does the number 3 truly affect the solution?
Yes—coefficients like 3 define how variables scale. In this case, the difference in growth rates between $ z $ on both sides drives the solution. This concept mirrors real-life balancing acts, such as cost projections or resource allocation.

Q: Can this problem apply outside school?
Absolutely. Solving for unknowns is foundational in financial planning, data analysis, and project forecasting—areas many U.S. professionals encounter regularly.
