Question

11 2/3x-5 1/6=3 3/4+2 3/4x; 12 3/4+3/7y=y/2-10 1/28; 6x+7/7=3-5x-3/8; 10-3x-1/2=6x+3/11;

Answer 1

11 2/3х - 5 1/6 = 3 3/4 + 2 3/4х
11 2/3х - 2 3/4х = 3 3/4 + 5 1/6
35/3х - 11/4х = 15/4 + 31/6
150/12х - 33/12х = 45/12 + 62/12
117/12х = 107/12 х
х = 117/12 : 107/12
х = 117/107
ответ: х = 117/107 = 1 10/107
