7 > −2x + 3 ≥ − 7 this can be split into two parts. 7>-2x+3 nd -2x+3≥-7 7>-2x+3 7-3>-2x 4>-2x When u divide by -2 the inequality sign flips 4/-2>-2x/-2 -2<x -2x+3≥-7 -2x≥-7-3 -2x≥-10 When u divide by -2 the inequality sign flips -2x/-2≥-10/-2 x \(\le\)5. Nw let us plot this in number line. |dw:1345267049131:dw| The circle at 5 is shaded bcos it says that x is less than or equal to 5.
