Найдите корень уравнения: ( 16 х - 170 ) +2 ( 7 х - 165 ) =85 х + 1400 - ( 56 х - 58)
(16x-170)+2*(7x-165) = 85x+1400-(56x-58) 16x-170+14x-330 = 85x+1400-56x+58 30x-500 = 29x+1458 30x-29x = 1458+500 x = 1958
(16 х - 170 ) +2 ( 7 х - 165 ) =85 х + 1400 - ( 56 х - 58) 16x - 170 + 14x - 330 = 85x + 1400 - 56x + 58 30x - 500 = 29x + 1458 30x - 29x = 1458 + 500 x = 1958
