One and two step equations

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step, typically by performing an inverse operation to isolate the variable.

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to isolate the variable, usually involving addition or subtraction followed by multiplication or division.

How do you solve the equation 3x - 7 = 32?

Back

To solve 3x - 7 = 32, add 7 to both sides to get 3x = 39, then divide both sides by 3 to find x = 13.

Front

What is the first step to solve x + 12 = -20?

Back

The first step is to subtract 12 from both sides to isolate x, resulting in x = -32.

Front

How do you solve the equation 3x = 27?

Back

To solve 3x = 27, divide both sides by 3 to find x = 9.

Front

What is the solution to the equation x = 10?

Back

The solution is simply x = 10, as it is already isolated.

Front

How do you solve for b in the equation b - 13 = 3?

Back

To solve for b, add 13 to both sides, resulting in b = 16.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What is the inverse operation of multiplication?

Back

The inverse operation of multiplication is division.

Front

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

Back

Isolating a variable means manipulating the equation to get the variable alone on one side of the equation.
