Algebra Vocabulary
The number that sits directly in front of a variable to multiply it. 5m
What is a coefficient?
Simplify the following expression: 5x + 3x + 2
What is 8x + 2 ?
To begin solving 3x + 5 = 20, you must first do this inverse (opposite) by executing this operation on both sides.
What is subtraction?
The operation is used to isolate the variable: 6x = 24.
What is division?
"Inverse" means:
Opposite
A standalone number in an expression or equation that contains no variables.
What is a constant?
Simplify the following expression: 10a - 3a + 4b
What is 7a + 4b ?
This is a 2-step equation, Solve:
2w + 12 = 30
What is 2w = 18 ?
The value of "m" that completes this equation:
5m = 30.
What is m = 6
The opposite of multiplication is.
What is: Division ?
The general term for opposite operations that undo each other, such as multiplication and division.
What are inverse operations?
Simplify the following expression: 6 + 5m - 2 + 2m
What is 7m + 4 (or 4 + 7m)?
To clear the constant term in 5m - 6 = 24, you must apply this specific operation.
(What must you do to both sides?)
What is the Addition Property of Equality
(or adding 6 to both sides)
In the equation 4p = 16, this is the technical name for the number 4 that we must divide out.
(Variable, Constant, Coefficient)
What is the coefficient ?
isolate the variable in the following two-step linear equation, then Solve:
2x + 5 = 15
What is: x = 5 ?
According to the "Sticky Sign Rule," this is where a term's operational sign (+ or -) is permanently located. 5a + 3b - 5a + 6
What is directly in front of the term?
Simplify the following expression, noting that the variable terms fully cancel out: 4x + 3y - 4x
What is 3y ?
or 0y + 3y ?
When applying the inverse to the equation
2k + 12 = 32, this is the resulting balanced equation or (simplified version)
What is 2k = 10 ?
2 x 10 + 12 = 32
- 12 - 12
20/2 = 10
To isolate the variable in w ÷ 3 = 6, you must apply this property of equality.
What is the Multiplication Property of Equality
(or multiplying both sides by 3)
Solve: 4w = 36
What is: 9 ?
The letter that represents a mystery number.
What is a “variable”
Simplify this massive expression containing three distinct families: 5x + 4y + 3 + 2x - y - 1
What is 7x + 3y + 2 ?
In the equation frac (w ÷ 3) + 4 = 10, this is the step you must take before dealing with the fraction.
What is subtracting 4 from both sides?
The complete, step-by-step solution sequence for the equation 6y - 8 = 40. hint: two steps
What is adding 8 (6y = 48),
then dividing by 6 (y = 8)?
or y = 8
Solve: w ÷ 3 = 6
What is w = 18
