Recall: We treat inequality in a similar manner to the equal sign. The steps are: 1. Collect like terms 2. Simplify 3x – 7 > 3 – x step 1 : 3x + x > 3+7 step 2: 4x > 10 4x/4 > 10/4 x > 2.5

Given, 8x - 8 = 2x + 10 Solution: To solve this kind of problem, the first step is to always collect the like terms together i.e. Take the terms with x to one side of the equal sign and the numbers to the ot...
