Is this a solution to the one-step equation?

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 the same operation on both sides of the equation.

Front

How do you solve the equation y - 14 = 66?

Back

Add 14 to both sides: y = 66 + 14, so y = 80.

Front

What is the solution to the equation n - 2 = 7?

Back

Add 2 to both sides: n = 7 + 2, so n = 9.

Front

How do you check if n = 9 is a solution to n - 2 = 7?

Back

Substitute 9 into the equation: 9 - 2 = 7, which is true.

Front

What is the solution to the equation r + 20 = 27?

Back

Subtract 20 from both sides: r = 27 - 20, so r = 7.

Front

How do you solve the equation x + 5 = 8?

Back

Subtract 5 from both sides: x = 8 - 5, so x = 3.

Front

What is the solution to the equation x + 12 = 20?

Back

Subtract 12 from both sides: x = 20 - 12, so x = 8.

Front

What does it mean for a number to be a solution to an equation?

Back

A number is a solution to an equation if, when substituted into the equation, it makes the equation true.

Front

What operation would you use to isolate the variable in the equation x + 4 = 10?

Back

You would subtract 4 from both sides.

Front

If you have the equation 3x = 12, how do you solve for x?

Back

Divide both sides by 3: x = 12 / 3, so x = 4.
