... Step 4: reach conclusion: because 7 = 7 is a true statement, thus x = 2 is the solution for 2x + 3 = 7 We found the solution through trial-and-error method. Next we will learn how to find the solution by actually solving an equation and not using trial and error method. ...

... Correct! If you divide both sides of the inequality by a negative number, reverse the inequality sign. If you divide by a positive number, do not reverse the sign. What inverse operations are needed to isolate the variable? Be careful with your calculations when using inverse operations to isolate t ...
