Q. Solve for x.5x−4≥12 AND 12x+5≤−4Choose 1 answer:(A) x≥516 or x≤−43(B) x≤516(C) x≥−43(D) There are no solutions(E) All values of x are solutions
Solve first inequality: Solve the first inequality 5x−4≥12.Add 4 to both sides to isolate the term with x on one side.5x−4+4≥12+45x≥16Now, divide both sides by 5 to solve for x.55x≥516x≥516
Solve second inequality: Solve the second inequality 12x+5≤−4.Subtract 5 from both sides to isolate the term with x on one side.12x+5−5≤−4−512x≤−9Now, divide both sides by 12 to solve for x.1212x≤12−9x≤−43
Combine solutions of both inequalities: Combine the solutions of both inequalities to find the common solution set.The first inequality gives us x≥516, and the second inequality gives us x≤−43. Since there is no overlap between these two sets (no x can be both greater than or equal to 516 and less than or equal to−43 at the same time), there are no solutions that satisfy both inequalities simultaneously.
