Practicing Variables on Both Sides

Front

What is a variable in an equation?

Back

A symbol, often a letter, that represents an unknown value in an equation.

Front

How do you isolate a variable in an equation?

Back

By performing inverse operations to get the variable alone on one side of the equation.

Front

What does it mean to solve an equation?

Back

Finding the value of the variable that makes the equation true.

Front

What is the first step in solving the equation 2x + 24 = 8x?

Back

Subtract 2x from both sides to begin isolating the variable.

Front

What is the solution to the equation 2x + 24 = 8x?

Back

x = 4.

Front

How do 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.

Front

What is the value of 'x' in the equation 3x + 2 = 2x - 8?

Back

x = -10.

Front

What is the process to solve the equation 3x = 15 - 2x?

Back

Add 2x to both sides, then divide by 5 to isolate x.

Front

What is the solution to the equation 3x = 15 - 2x?

Back

x = 3.

Front

What does it mean when an equation has variables on both sides?

Back

It means you need to manipulate the equation to get all variables on one side.
