This week we mainly focused on methods on how to solve equations. We covered 4 different ways, however, the main ones that normally are used to solve algebraically are substituition and elimination.
- Elimination mainly focuses on creating zero pairs. This is very helpful when all the variables have a coefficent that is not equal to 1. I will show an elimination equation below.
- Substitution is used to take numbers of one equation and place them into another equation.
Elimination:
Step 1: Find zero pairs
Step 2: Add zero pairs and other numbers together
Step 3: Continue adding and find the end result
Step 4: Reduce/divide fractions by -13, and here you have your final ‘y’ value
