Question: Write 3 (algebraic) equations that you know have the same solution (Explain how you know!)

 

And...

An expression decreases in value by 5 if x increases in value by 1. What could the expression be?

To get three equations with the same solution -- start with the answer that you want, say 3.

1)      2x  =  6

2)      x + 1  =  4

3)      x - 1  =  2

 

An expression that decreases by 5 if x increases by 1

        -5x

 

if x = 1, -5x = -5

if x = 2, -5x = -10

if x = 3, -5x = -15

etc.
