Question

|3x-1 supra 5 + x-1 supra 3 -5x supra 9| = 8 (e modul)

Answer 1

|3x-1/5+x-1/3-5x/9|=8 => numitorul comun - 45

| 9(3x-1)+15(x-1)-25x| = 45•8

|27x-9+15x-15-25x| = 360

|27x-10x-24|=360

|17x-24|=360

=> (17x-24)=360 => 17x-24=360=>17x=360+24=>

x = 384:17=> x=384/17

=> -(17x-24)=360 => -17x+24=360=>-17x=336=> x =-336/17
