Q. Solve for x.−15x+60≤105 AND 14x+11≤−31Choose 1 answer:(A) x≤−3(B) x≥−3(C) x=−3(D) There are no solutions(E) All values of x are solutions
Solve first inequality: Solve the first inequality −15x+60≤105.Subtract 60 from both sides to isolate the term with x.−15x+60−60≤105−60−15x≤45Now, divide both sides by −15 to solve for x. Remember that dividing by a negative number reverses the inequality sign.−−1515x≥−1545x≥−3
Solve second inequality: Solve the second inequality 14x+11≤−31.Subtract 11 from both sides to isolate the term with x.14x+11−11≤−31−1114x≤−42Now, divide both sides by 14 to solve for x.1414x≤14−42x≤−3
Combine solutions: Combine the solutions from Step 1 and Step 2 to find the common solution set.From Step 1, we have x≥−3.From Step 2, we have x≤−3.The common solution that satisfies both inequalities is x=−3.
