Solve each equation. Then determine whether the equation is an identity, a conditional equation, or an inconsistent equation. $$\frac{3}{x-3}=\frac{x}{x-3}+3$$

In Exercises 61鈥�78, solve each absolute value equation or indicate that the equation has no solution. $$3|2 x-1|=21$$

The price of a dress is reduced by \(40 \% .\) When the dress still does not sell, it is reduced by 40 \% of the reduced price. If the price of the dress after both reductions is \(\$ 72,\) what was the original price?

In Exercises 59鈥�94, solve each absolute value inequality. $$ \left|\frac{3(x-1)}{4}\right|<6 $$

Determine whether each statement makes sense or does not make sense, and explain your reasoning. There is something wrong with my graphing utility because it is not displaying numbers along the \(x\) - and \(y\) -axes.

Combine the types of equations we have discussed in this section. Solve equation. Then state whether the equation is an identity, a conditional equation, or an inconsistent equation. $$\frac{x+5}{2}-4=\frac{2 x-1}{3}$$
