LT 1-3: Solving Equations With a Variable on Both Sides
LT 1-3: Solving Equations With a Variable on Both Sides
The properties of equality are used to solve equations that have variables on each side. If an equation is true for all values of
x, then it has infinitely many solutions; if it is not true for any value of x, then it has no solutions.
