A one-step equation is an equation that can be solved in one operation, such as addition, subtraction, multiplication, or division.

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, allowing you 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.

Front

If x + 4 = 10, how do you isolate x?

Back

Front

If y - 3 = 5, how do you isolate y?

Back

Add 3 to both sides. The solution is y = 8.

Front

What is the solution to the equation 2x = 10?

Back

Divide both sides by 2. The solution is x = 5.

Front

What is the solution to the equation x/4 = 3?

Back

Multiply both sides by 4. The solution is x = 12.

Front

In the equation x + 5 = 15, what is the value of x?

Back

Subtract 5 from both sides. The solution is x = 10.

Front

What does it mean to check your solution in an equation?

Back

Checking your solution means substituting the value back into the original equation to verify that both sides are equal.
