It looks like you've uploaded a worksheet titled
"Solving Systems of Three Equations by Substitution", and it contains several systems of three equations in three variables (x, y, z). However, I can't view images directly.
To help you solve the problems, please provide the
text of the equations from the worksheet — for example, list the systems one by one (e.g., equations 1–3, 4–6, etc.), or describe what's written.
Once I have the actual equations, I can walk you through solving each system using
substitution, step-by-step, with explanations.
For now, here’s how we generally solve a system of three equations using substitution:

🔷 General Steps for Solving a System of Three Equations by Substitution:
1.
Solve one equation for one variable (e.g., solve for x in terms of y and z).
2.
Substitute that expression into the other two equations to eliminate that variable.
3. Now you’ll have a
system of two equations in two variables (y and z).
4. Solve this smaller system using substitution or elimination.
5. Once you find the values of two variables,
back-substitute to find the third.

Please reply with the equations from your worksheet (e.g., write them out), and I’ll solve them for you!
