2.3 MAT1033 Lecture Notes Solving Linear Equations Tips: When solving an equation containing fractions, be sure to multiply every term by the LCD. You can check the solution by substituting it back into the original equation. If the final step in solving an equation contains no variable, and it is a false statement, then there is no solutionto the equation. We use { } or to represent empty set or null set. If the final step in solving an equation contains no variable, and it is a true statement, then we conclude that all real numbers are solutions. {all real numbers} --------------------------------------------------------------------------------------------------------------------------------------Ex1. 51124xxEx2. 0.60(300)0.050.70205zzzEx3. 2(65)41214xx Ex4. 5(43)22013yy 
