 2x + 3y < -3 ⇒   2x + 3y = -3 ⇒    2x + 3y = -3
-4x +   y ≥ 2  ⇒ -4x +    y =  2 ⇒ <u>-12x + 3y =  6</u>
                                                            <u>-14x</u> = <u>-9</u>
                                                             -14    -14
                                                                 x = ⁹/₁₄
                                                       2x + 3y = -3
                                                  2(⁹/₁₄) + 3y = -3
                                                     1²/₇ + 3y = -3
                                                   <u>- 1²/₇            - 1²/₇
</u>                                                               <u>3y</u> = <u>-4²/₇
</u>                                                                3        3
                                                                 y  = -1³/₇
                               The solution set is {(⁹/₁₄, -1³/₇)}.
