We then shade in all the numbers to the left of one, to show that all numbers less than one are solutions (Figure \(\PageIndex{3}\)). This leads to the following new rule: when multiplying or dividing by a negative number, reverse the inequality. We do that by putting a bracket at \(x=1\). Html format: simply refresh the worksheet page in your browser window. Step 2: Identify the variables by assigning a letter or expression to the unknown quantities. If given fractional coefficients, then multiply both sides of the equation by the least common multiple of the denominators (LCD). In interval notation, we express \(x>3\) as \((3,\infty)\). We use these properties to obtain an equivalent inequality141, one with the same solution set, where the variable is isolated. Finally, check to verify that your solution solves the original equation.
