x+|5|=-23

=>x+5=-23

=>x=-23-5

=>x=-28

vậy............

x + | 5 | = -23

    x + 5 = -23

          x  =( -23 ) - 5

          x  = -28

tk nhé  

kb với mình đi

x + 67 = 89 - 45

x + 67 = 44

        x = 44 - 67 

        x = - 23

k mk nha

thank you very much

x + 67 = 89 - 45

x + 67 = 44

x = 44 - 67

x = -23

x + 67 = 44

      x=44+ 67
