If when you solve, the x's cancel and you are left with something like 5=5 that means there are an infinite number of solutions. This means that any number you choose will work. If you are left with something false like 0 =5, then there are no solutions.
5x -15 + 6 = 5x - 9
-9 = -9 True.. Infinite number of solutions.
Try substituting "0", "1", "10" and you will see that all three work.
tell whether each equation has one solution, zero solutions or infinite solutions
5(x-3)+6=5x-9
