Solving One Step Equations Flashcard 1-20-21

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 x + 12 = 20?

Back

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

Front

What is the solution to the equation y - 4.6 = 12?

Back

Add 4.6 to both sides: y = 12 + 4.6, so y = 16.6.

Front

Which equation has x = 5 as the solution?

Back

The equation 2x = 10 has x = 5 as the solution.

Front

How do you solve the equation x ÷ 2 = 12?

Back

Multiply both sides by 2: x = 12 * 2, so x = 24.

Front

What is the first step in solving the equation x - 5 = 10?

Back

Add 5 to both sides: x = 10 + 5, so x = 15.

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 and all other terms are on the other side.

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.

Front

What is the solution to the equation 3x = 12?

Back

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

Front

What operation would you use to solve the equation x - 7 = 3?

Back

Add 7 to both sides: x = 3 + 7, so x = 10.
