How do you simplify the expression -3(x + 7)?

Back

To simplify -3(x + 7), distribute -3 to both x and 7, resulting in -3x - 21.

Front

What is the solution to the equation -10k = 50?

Back

To solve -10k = 50, divide both sides by -10, resulting in k = -5.

Front

How do you solve the equation -4x = -36?

Back

To solve -4x = -36, divide both sides by -4, resulting in x = 9.

Front

What is the solution to the equation x + 4 = -3?

Back

To solve x + 4 = -3, subtract 4 from both sides, resulting in x = -7.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means rearranging the equation so that the variable is on one side and all other terms are on the opposite side.

Front

What is the first step in solving a one-step equation?

Back

The first step is to perform the inverse operation to eliminate the constant or coefficient from the variable.

Front

What is an example of a one-step equation?

Back

An example of a one-step equation is x + 5 = 10.

Front

How do you solve the equation x - 3 = 2?

Back

To solve x - 3 = 2, add 3 to both sides, resulting in x = 5.

Front

What is the solution to the equation 2y = 16?

Back

To solve 2y = 16, divide both sides by 2, resulting in y = 8.
