How do you solve the equation x - 15 = 60?

Back

To solve for x, add 15 to both sides: x = 60 + 15, which simplifies to x = 75.

Front

What is a variable in an equation?

Back

A variable is a symbol, often represented by a letter, that stands for an unknown value in an equation.

Front

What does it mean to isolate a variable?

Back

Isolating a variable means manipulating the equation to get the variable alone on one side of the equation.

Front

How do you solve the equation 5x = 20?

Back

To solve for x, divide both sides by 5: x = 20 / 5, which simplifies to x = 4.
