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 step by performing an inverse operation to isolate the variable.

Front

What operation is used to isolate a variable when it is being divided by a number?

Back

Multiply both sides of the equation by that number.

Front

Solve the equation: 3x = 15

Back

x = 5

Front

In the equation x - 4 = 10, how do you isolate x?

Back

Add 4 to both sides. The solution is x = 14.

Front

What is the solution to the equation: 5y = 25?

Back

y = 5

Front

If 2z + 6 = 14, how do you isolate z?

Back

Subtract 6 from both sides, then divide by 2. The solution is z = 4.

Front

What does it mean to isolate a variable?

Back

To isolate a variable means to manipulate the equation so that the variable is on one side by itself.

Front

Solve the equation: x + 9 = 20

Back

x = 11

Front

In the equation 12 = 3m, how do you solve for m?

Back

Divide both sides by 3. The solution is m = 4.

Front

What is the first step to solve the equation: n/4 = 3?

Back

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