What is this?
This is a tied knot
Esto es un nudo atado
4
What do you think the goal of this picture is?
To untie or undo the knot
El objetivo de esta imagen es desatar o deshacer el nudo.
5
The Main Goal to Solving Equations:
Isolate the variable/Aislar la variable
Get the variable by itself/Obtener la variable por sí sola
You can ONLY do this by UNDOING the operation/SOLO puede hacer esto DESHACER la operación
6
Solve using Inverse
operations
Inverse Operations undo each other
The inverse/opuesto of addition/adición is...
Subtraction/sustracción
The inverse/opuesto of subtraction/sustracción is....
Addition/adición
7
What does this Equation say???
A number minus 3 equals 6.
To isolate the variable we must perform the inverse operation of subtraction. Para aislar la variable debemos realizar la operación opuesto de resta.
Adding 3 to both sides of the equal sign will balance this equation. Sumar 3 a ambos lados del signo igual equilibrará esta ecuación.
X is equal to 9

What does this Equation say???
A number plus 3 equals 6.
To isolate the variable we must perform the inverse operation of addition. Para aislar la variable debemos realizar la operación opuesto de suma.
Subtracting 3 to both sides of the equal sign will balance this equation. Restar 3 a ambos lados del signo igual equilibrará esta ecuación.
X is equal to 3

Addition is...commutative!! It does not matter what order the numbers are in, they still show the same value. We still must isolate the variable by doing the opposite or inverse operation.
