Question

Solve the inequality. (solve interval form)
2x+2/4 - 2x-5/7 _<_ 5

campbell_st · Answer

multiply through be 28   the 7(2x + 2) - 4(2x - 5) < 140

expand and simplify        14x + 14 - 8x - 20 <140
                                            6x - 8 < 140

or                                         3x - 4 < 70
            
                                              3x < 74

                                                x<74/3

Unsure as to whether the inequality is <= or just <... but the maths appears correct

oops should read 14x + 14 - 8x + 20 < 140
                                6x + 34 < 140
                                 3x < 87
                                   x<29
