WRITE THE EQUATION REPRESENTED BY THE MODEL.
XXX + + + = XX - - -
3X + 3 = 2X - 3
check:
3X-2X = -3-3
X=-6
3(-6)+3 = 2(-6)-3
-15 = -15
In order to write the equation represented by the model, let's break down the given model into separate components and examine each one:
XXX + + + = XX - - -
Based on the model, we have the following components:
1. XXX: This represents a number or variable with three repeated characters. Let's assume this is a variable and represent it as "x."
2. + + +: This represents three consecutive positive additions. We can write this as "+ 3."
3. XX: This represents a number or variable with two repeated characters. Let's assume this is a variable and represent it as "y."
4. - - -: This represents three consecutive negative subtractions. We can write this as "- 3."
Now, let's put all the components together to form the equation:
x + 3 = y - 3
Therefore, the equation represented by the given model is "x + 3 = y - 3."
