WebSep 27, 2024 · Start the solution process as before, and at the end, you can move the variable to the left to write the final solution. Divide both sides by − 12 to isolate the variable. Since you are dividing by a negative number, you need to change the direction of the inequality sign. − 1 2 > − 12x − 1 2 − 12 > − 12x − 12. WebBut these things do change the direction of the inequality ("<" becomes ">" for example): Multiply (or divide) both sides by a negative number Swapping left and right hand sides

WebStep 1: Identify two inequalities that are given in the given inequality. Step 2: Solve each of them just like how we solve a normal inequality. Note that the procedure of solving an inequality is as same as solving an equation but just reverse the sign of inequality when you are multiplying or dividing the inequality by a negative number. small tupperware cupsWebOct 6, 2024 · Step 2: Set the argument of the absolute value equal to ± p. Here the argument is 5x − 1 and p = 6. 5x − 1 = − 6 or 5x − 1 = 6. Step 3: Solve each of the resulting linear equations. 5x − 1 = − 6 or 5x − 1 = 6 5x = − 5 5x = 7 x = − 1 x = 7 5.
