100
The definition of solve.
What is isolate the variable?
100
Solve and show work. 2 + x = 7
What is x=5?
100
Solve and show work. 4x = 20
What is x = 5?
100
This is the side you use to start solving the equation.
What is the side with the variable?
100
This was done wrong. 2x = 15 /2 | *2 x = 30
What is did not do the same thing to both sides?
200
The definition of variable.
What is a letter used to represent a number?
200
Solve and show work. x - 8 = 16
What is x=24?
200
Solve and show work. x/5 = 8
What is x=40?
200
These allow you to do the same things to both sides.
What are the Properties of Equality?
200
This was done wrong. x/3 = 9 /3 | /3 x = 3
What is not doing the opposite operation?
300
When you add the same thing to both sides of an equation, the value of the equation does not change.
What is the Addition Property of Equality?
300
The property needed to isolate the variable in this equation: x + 12 = 10
What is the Subtraction property of equality?
300
Solve and show work. 15x = 60.
What is x=4?
300
This is how you determine what number to add, subtract, multiply, or divide by.
What is the number with the variable?
300
This was done wrong. 6x = 48 /6 | /6 x = 42
What is evaluating wrong or 48 divided by 6 does not equal 42?
400
If you divide the same thing from both sides of the equation, the value of the equation does not change.
What is the Division Property of Equality?
400
Solve. x - 9 = 18
What is x = 27?
400
Solve and Show work. x/10 = 8
What is x=80?
400
This is why you know your answer is correct.
What is checking your answer or substituting your answer into the equation?
400
This was done wrong. x/7 = 9 -7 -7 x = 2
What is not doing the opposite operation?
500
This allows you to multiply both sides of the equation in order to isolate the variable.
What is the Multiplication Property of Equality?
500
The x in ... 17 + x = 22
What is x = 5?
500
Solve and show work. 7x = 56
What is x=8?
500
This is what you do when you are isolating the variable in the equation.
What is solving an equation?
500
This was done wrong. 7x = 35 /35 /35 x = 7/35 x = 1/5
