One way of thinking about solving equations is to work to get the variable terms on one side of the equation and the constants on the other side. Consider the equation
As a first step, you could subtract
from both sides, or divide both sides by , or add to both sides of the equation. Does one of these steps get all of the variable terms on one side of the equation and the constants on the other?
Try each of the operations above. Which operation isolates the variable and a constant on separate sides of the equation?
