Solving 1-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 involving addition, subtraction, multiplication, or division.

Front

How do you solve the equation x + 5 = 12?

Back

Subtract 5 from both sides: x = 12 - 5, so x = 7.

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

How do you solve the equation 3x = 15?

Back

Divide both sides by 3: x = 15 / 3, so x = 5.

Front

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

Back

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

Front

How do you solve the equation x - 4 = 10?

Back

Add 4 to both sides: x = 10 + 4, so x = 14.

Front

What is the solution to the equation x/2 = 6?

Back

Multiply both sides by 2: x = 6 * 2, so x = 12.

Front

What is a variable in an equation?

Back

A variable is a symbol, often represented by a letter, that stands for an unknown value.

Front

How do you check the solution of an equation?

Back

Substitute the solution back into the original equation to see if both sides are equal.
