Lesson 7:For all equations: If the equation has one solution, enter that answer. If there is no solution to the equation, enter “none”.If all real numbers are solutions to the equation except for those value(s) that make the denominators zero, enter 1,...xaFor example, in #4, we get equations that look like 142184xx(this is called an “identity,”because we get the same thing on both sides after cross-multiplication) and thus all real numbers are solutions except for any number that makes any denominator zero (in this case, 12). Enter this type of answer on the computer as 12x. If there are two values for which the denominator will be zero, enter as 12xor as 11,22. The plus/minus option is listed under the “log” menu. Do NOT enter as ,x. Cengage Now cannot accept this format. #1:
