Solve a linear equation symbolically (literal equation), numerically, graphically.
• How do you solve a linear equation numerically?
• How do you solve a literal equation symbolically?
• How do you solve an equation graphically?
• How do you solve q = P(t) = at + b for t?
• How do you solve for t in q = R(t) = at - (bt + c)?
• How do you solve an equation using the equation solver on a TI graphing calculator?
This lesson will show you three different ways of solving linear equations. You may already know how to solve an equation numerically and graphically, but you will also learn in this lesson how to solve an equation symbolically. This is called a literal equation, and you will simply solve for one of the symbols in an equation where there are no (or very few) numbers.
