Predict how many solutions a linear equation has
In this lesson you will learn to predict how many solutions a linear equation has by identifying key features of equations.
Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).
