1. 2 Step Equations
Grade 6 Algebra Unit

2. Recap... - What is a variable? - What do we know about equations?
- What is the order of operations

3. Minds on... Find the solution where x=5 - 3(x+6) - (15-x)÷2

4. Minds on...
Solve for x
- x+15=27
- 6x=42
-2x+5=25

5. Can we find the value of one variable (x) when there are two variables in the equation (x) and (y)?
Ex. 3(x+y)=27

6. If we are given the value of one variable (y), we can find the value of another variable (x).
Let’s say y= 4, how could we solve for x?
3(x+y)=27

7. You need to insert the value of the known variable (y) into the equation, then isolate for the unknown variable (x).
y= 4
3(x+y)=27

8. Try these...
Solve for x, where y= 4
2y+3x=23
2x-2y=2
