Решите уравнение:
а. 8x + x – 3x = 108;
б. (16x – 10x + 3) ∙ 4 = 132.

а) 8х +х – 3х = 1089х – 3х = 108 6х = 108 х = 108:6х = 188*18 + 18 – 3*18 = 108108 = 108Ответ: 18б) (16х – 10х + 3)*4 = 13216х – 10х + 3 = 132 : 416х – 10х + 3 = 336х = 33 – 36х = 30х = 30 : 6 х = 5( 16*5 – 10*5 + 3 ) * 4 = 132132 = 132Ответ : 5
