Refresher using DESMOS

IXL: Solve Multi-Step Equations

Code: 28N
Smart Score: 75

Example: f - 4 = 6f + 26

Step 1: Replace all variables with an x

x - 4 = 6x + 26

Example: f - 4 = 6f + 26

Step 2: Type the left side into the first line of desmos

x - 4

Example: f - 4 = 6f + 26

Step 3: Type the right side into the first line of desmos

6x + 26

Example: f - 4 = 6f + 26

Step 4: Find the point of intersection. The answer is the x-value.
Remember (x,y)

f=-6

No Solution v. All Real Numbers

No Solution - the lines will never cross each other (parallel)

All Real Numbers - the lines are the same or will overlap at every point
