Best ResponseYou've already chosen the best response.1Solve separately the expression 5x3 as +(5x3) and (5x3), which means you have two solutions. solve (1/9)(5x3)\(\ge\)2 and (1/9)(5x3)\(\ge\)2 to get the two required solutions.

Best ResponseYou've already chosen the best response.1Yes, that's ok too!, now put the expression as 5x3 and (5x3) and solve the equations.

Best ResponseYou've already chosen the best response.1but (1/9)(5x3)3≥2 => (5x3)27≥18 and (1/9)(5x3)3≥2 => (5x3)27≥18

Best ResponseYou've already chosen the best response.1Add 27 to both sides, we have (5x3)27+27≥18+27 (5x3)27+27≥18+27 or 5x3≥45 and 5x+3≥45 solve accordingly.
