The Power of Equations
Don't let the letters in algebra scare you. They're just placeholders, standing in for an unknown number. And, great news, when those letters show up in an equation, you've got everything you need to solve the mystery and reveal x's true identity!
LEARN IT
To solve an equation is to determine what value of the variable makes the equation true. We do this by isolating the variable, in other words getting the letter alone, using inverse or opposite operations.
