Back

-5

Front

What is the solution to the equation 5(x + 2) = 7(4 - x)?

Back

1.5

Front

What property of real numbers justifies the work shown in an equation?

Back

Commutative property of addition

Front

Solve for x: -2x + 6 < x - 6

Back

x > 4

Front

Which inequality is equivalent to 4x - 2y ≤ 8?

Back

y ≥ 2x - 4

Front

Define the Commutative Property of Addition.

Back

The Commutative Property of Addition states that changing the order of the addends does not change the sum. (a + b = b + a)

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation until the variable is alone.

Front

What does it mean for an inequality to be equivalent?

Back

Two inequalities are equivalent if they have the same solution set.

Front

What is the solution to the inequality 2x + 3 > 7?

Back

x > 2.
