One 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 operation, such as addition, subtraction, multiplication, or division.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform the inverse operation on both sides of the equation to get the variable by itself.

Front

What is the solution to the equation 2y = 18?

Back

y = 9

Front

How do you solve the equation 13 + y = 20?

Back

Subtract 13 from both sides to isolate y: y = 20 - 13, so y = 7.

Front

What is the solution to the equation n - 4 = 12?

Back

Add 4 to both sides to isolate n: n = 12 + 4, so n = 16.

Front

How do you simplify the equation 4 = 4m - 2m?

Back

Combine like terms on the right side: 4 = 2m, then divide both sides by 2 to find m = 2.

Front

What is the solution to the equation 6y = 42?

Back

Divide both sides by 6 to isolate y: y = 42 / 6, so y = 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 can you check if your solution to an equation is correct?

Back

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