one and 2 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 one 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 both addition/subtraction and multiplication/division.

Front

How do you solve the equation z - 6 = 13?

Back

Add 6 to both sides: z = 13 + 6, so z = 19.

Front

What is the solution to the equation 2x = 8?

Back

Divide both sides by 2: x = 8 / 2, so x = 4.

Front

What is the first step to solve the equation p + 8 = 12?

Back

Subtract 8 from both sides: p = 12 - 8, so p = 4.

Front

How do you solve the equation x - 4 = 9?

Back

Add 4 to both sides: x = 9 + 4, so x = 13.

Front

What is the solution to the equation 9x + 1 = 10?

Back

Subtract 1 from both sides: 9x = 10 - 1, then divide by 9: x = 9 / 9, so x = 1.

Front

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

Back

Isolating a variable means to manipulate the equation so that the variable is on one side by itself, making it easier to find its value.

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.
