1. Решите уравнение:
1) 4 5/23 + х = 10 2/23
2) 7 9/16 - ( х - 2 3/16 ) = 4 11/16

х=10 2/23-4 5/23х=9 25/23-4 5/23х=5 20/23проверка4 5/23+5 20/23=10 2/239 25/23=10 2/2310 2/23=10 2/237 9/16-х+2 3/16=4 11/169 12/16=9 3/4+х=4 11/16х=9 3/4-4 11/16х=9 12/16-4 11/16х=5 1/16проверка7 9/16-(5 1/16-2 3/16)=4 11/167 9/16-2 14/16=4 11/166 25/16-2 14/16=4 11/164 11/16=4 11/16
