Example: Solving and Graphing 4b3(3b)>5(b6)+2b4b - 3(3 - b) > 5(b - 6) + 2b

To solve the linear inequality 4b3(3b)>5(b6)+2b4b - 3(3 - b) > 5(b - 6) + 2b, systematically simplify both sides heavily by distributing, extracting 4b9+3b>5b30+2b4b - 9 + 3b > 5b - 30 + 2b. Combining corresponding like terms accurately returns 7b9>7b307b - 9 > 7b - 30. Subtracting 7b7b logically from both sides completely zeroes out the variable terms and leaves only 9>30-9 > -30. Since this denotes an inherently true mathematical statement irrespective of variables, the unique inequality robustly functions as an identity boasting an infinite solution of all real numbers. The entire number line is permanently shaded for accurate geometric representation, natively defining (,)(-\infty, \infty) in standard interval notation.
