First, use the inverse operations. Then, work backwards to undo each operation one at a time by doing the reverse order of operations.
What would be a good explanation for how to solve a two-step equation?
100
6x = 4x - 10
-4x -4x (Subtract 4x from each side) and you get
2x = -10
/2 /2 (Divide by 2 on each side) and you get
x = -5
What is an example of solving an equation with variables on both sides?
100
Both use properties of equalities.
What is the comparison between solving one-step equations by adding/subtracting and solving one-step equations by multiplying/dividing?
100
To accurately solve equations.
Why is it important for students to learn the properties of real numbers and the properties of equalities?
200
Multiplication
What is the inverse operation of division?
200
a = b
a + c = b + c
How do you translate the Addition Property of Equality from words into variables?
200
A student can write an equation with like terms that need to be combined.
How can a student construct a multi-step equation?
200
Some one-step equations use the addition or subtraction properties of equalities, and others use the multiplication and division properties of equalities.
What is a difference when solving one-step equations?
200
A student who understands the vocabulary words in math will better understand the lesson.
Why is it important for students to learn the vocabulary words, such as equivalent equations, before starting a math lesson?
