Peшите уравнения: 2-(3x-7)/4+(x+17)/5=0 (4x+7)/5+(3x-2)/2-(5x-2)/2=32

(- 3x + 9) / 4 = - ( x + 17) / 5 ( - 3x + 9) / 4 = ( - x - 17) / 5 5 ( - 3x + 9) = 4( - x - 17) - 15x + 45 = - 4x - 68 - 15x + 4x = - 45 - 68 - 11x = - 113 11x = 113 x = 113/11 x = 10целых 3/11 приводим к общему знаменателю и решаем: ( 8x + 14 + 15x - 10 - 25x + 10) / 10 = 32 ( - 2x + 14) / 10 = 32/1 - 2x + 14 = 32 × 10 - 2x + 14 = 320 - 2x = 320 - 14 - 2x = 306 2x = - 306 x = - 306/2 x = - 153
