Final answer:
The general process to solve multi-step equations involves identifying the unknown, the knowns, and using an equation to solve for the unknown. Simultaneous equations may require substitution and algebraic manipulation. The specific code for the digital escape room puzzle is not provided here.
Step-by-step explanation:
Solving multi-step equations typically involves a systematic approach. While I don't have the specific code for the digital escape room puzzle 3, I can guide you through the general process of solving such puzzles:
- Identify the unknown: Determine what you are trying to find.
- Identify the knowns: Gather all the information provided by the problem.
- Choose an equation, plug in the knowns, and solve for the unknown.
When it comes to simultaneous equations, as the hint suggests, you may need to:
- Solve the equations for a variable (Y or AE).
- Substitute the value of the solved variable into the other equation.
- Solve the simultaneous equations for the unknowns.
The strategy generally requires careful checking of your algebraic steps. If you are using a calculator like the TI-83, 83+, or 84, you can utilize its functions to find solutions more efficiently.
