The temperature at noon in Los Angeles on a summer day was $88^{\circ} \mathrm{F}$. During the day, the temperature varied from this by as much as $7.5^{\circ} \mathrm{F}$. Give and solve an absolute-value inequality to determine the range of possible temperatures for that day.

Solve for x: a. 2x - 3 = x + 6 b. 4x - 2 = 5 - x c. 4 - 5x = 3x - 7 d. -x = x + 4 e. 12 - 7x = 3x + 8 f. 5x - 9 = 1 + 6x g. 4 - x - 3(2 - x) = 6 + x h. 5 - 3(1 - x) = 2 - x i. 3 - 2x - (2x + 1) = -1 j. 3(4x + 2) - 2x = -7 + x

Indicate whether the value, m = 12; 5m + 4 > 50, is a solution to the inequality. Discuss.
