Solving 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, typically involving addition, subtraction, multiplication, or division.

Front

How do you solve the equation 4x = 8?

Back

Divide both sides by 4: x = 8/4, so x = 2.

Front

What is the solution to the equation 8x = 32?

Back

Divide both sides by 8: x = 32/8, so x = 4.

Front

How do you solve the equation 9 + x = 18?

Back

Subtract 9 from both sides: x = 18 - 9, so x = 9.

Front

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

Back

Multiply both sides by x: 10 = 2x, then divide by 2: x = 10/2, so x = 5.

Front

How do you solve the equation 7 + x = 15?

Back

Subtract 7 from both sides: x = 15 - 7, so x = 8.

Front

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

Back

Isolating the variable means to manipulate the equation so that the variable is on one side by itself.

Front

What operation would you use to solve the equation x - 3 = 5?

Back

Add 3 to both sides: x = 5 + 3, so x = 8.

Front

What is the first step to solve the equation 5x = 25?

Back

Divide both sides by 5: x = 25/5, so x = 5.

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.
