Answers
1
What does the teacher mean by "isolating the variable"?
Changing the variable to a different letter
Removing the variable from the equation
Getting the variable by itself on one side of the equation
Making the variable negative
2
What is the purpose of plugging the solution back into the original equation?
To make the problem longer
To check if the answer is correct
To practice multiplication
To create a new equation
3
In the equation R ÷ 5 + 8 = 11, what is the final step to solve for R?
Subtrat 8 from both sides
Add 11 to both sides
Divide both sides by 5
Multiply both sides by 5
4
In the equation 7 = 16 - 3e, why does the teacher subtract 16 from both sides?
Because 16 is larger than 7
To move the variable to the left side
To make the numbers smaller
To get rid of the 16 on the right side
5
Why does the teacher suggest using the "reverse order of operations" when solving equations?
Because it's faster
To make the problem more difficulth
To create more steps in the solution
To undo the operations and isolate the variable
6
Which mathematical principle is important to remember when solving equations?
Always add 5 to both sides
whatever you do to one side, you must do to the other side
multiply all numbers by 2
only change one side of the equation
7
What is the main goal when solving an equation with a variable?
To remove allnumbers
To add more variables
To make the equation longer
To isolate the variable
8
In the equation 2(y - 8) = 24, why is dividing both sides by 2 the first step?
To undo the multiplication outside the parentheses
Because 24 is even
Because 2 is the smallest number
To get rid of the parentheses
9
In the equation 2x - 6 = 10, what is the first step to solve for x?
Divide both sides by 2
Add 6 to both sides
Subtract 10 from both sides
Multiply both sides by 2
10
Which of the following best describes the process of solving two-step equations?
Combine like terms on both sides.
Undo operations in reverse order to isolate the variable
Always add then multiply
Guess and check until you find the right answer
