Example: A + B = C. Here is a formula with 3 variables and an operation (addition).
Word problem using the example: There are 2 dogs: One dog eats 2 snacks and the other dog eats 5 snacks. What is the total number of the snacks eaten by the 2 dogs?
Let the first dogs snacks be represented by the variable A and let the second dogs snacks be represented by the variable B., and the total number of snacks eaten by the 2 dogs be represented by the variable C.
---
A (The first dogs snacks.) + B (The second dogs snacks.) = C ( The total number of snacks eaten by the 2 dogs.) 2 snacks eaten + 5 snacks eaten = 7 snacks eaten. . A + B = C, A = 2, B = 5, 2 + 5 = 7, C = 7.
----
If you knew the total snacks eaten and also knew the number of snacks eaten by one dog, your equation would look something like this.
C(Total snacks eaten), A( first dogs snacks), B(second dogs snacks. unknown.)
A + B = C, 2 + B = 7, B = [ 7 - 2], B = 5.

How do you evaluate equations?
To evaluate means to find the value. Substitute the values of the variables and calculate the value. [You may need to solve for the values of the variables first.]
What do variables allow you to do tht you couldn't before?
In programming: They let you do generic calculations, with numbers that you don't know in advance. In algebra: They let you do calculations with unknown values - either generic calculations, or do calculations to find such unknown values in a specific case.
How do you find 2 missing numbers in equivalent fractions?
To find two missing numbers in equivalent fractions, you can set up an equation using the property that two fractions are equivalent if their cross products are equal. For instance, if you have the fractions ( \frac{a}{b} ) and ( \frac{c}{d} ), you can use the equation ( a \times d = b \times c ) to find the missing values. By substituting known values into this equation, you can solve for the unknowns. Additionally, you can also use a common multiplier or divisor to scale the fractions up or down to find the missing numbers.
How do you solve a order pair?
To solve an ordered pair, you typically need to determine the values of the two variables it represents, usually denoted as (x, y). This can involve substituting the values into an equation or system of equations to find a solution that satisfies both conditions. If you're dealing with a graph, the ordered pair can represent a point where the two axes intersect. Ensure that the values make sense in the context of the problem you are solving.
How do you find an equivalent expression?
To find an equivalent expression, you can use algebraic manipulation techniques such as factoring, distributing, combining like terms, or applying the properties of operations (like the distributive property or the associative property). Simplifying complex expressions or rewriting them in different forms can also help identify equivalence. Additionally, substituting values for variables can verify if two expressions yield the same result. Always ensure that any transformations maintain the original expression's value for all permissible values of the variables involved.
How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?
