Answer 1

Ответ:

Пошаговое объяснение:

3 - ( х - 3/10) - 5/7 = 24/35 - 1/10

3 - ( х - 3/10) - 5/7 = 48/70 - 7/70

3 - (х - 3/10) - 5/7 = 41/70

х- 3/10 =  2 2/7- 41/70

х - 3/10 = 16/7 - 41/70

х - 3/10 =  160/70 -41/70

х- 3/10 =  119/70

х=  119/70 + 3/10

х=  119/70 + 21/70

х= 140/70

х= 2

Пошаговое объяснение:

3 - (х - 3/10) - 5/7 = 24/35 - 1/10

3 - (х - 3/10) - 5/7 = 48/70 - 7/70

3 - (х - 21/70) - 50/70 = 41/70

3 - (х - 21/70) = 41/70 + 50/70

3 - (х - 21/70) = 91/70

3 - (х - 21/70) = 1. 21/70

х - 21/70 = 3 - 1. 21/70

х - 21/70 = 2. 70/70 - 1. 21/70

х - 21/70 = 1. 49/70

х = 1. 49/70 + 21/70

х = 1. 70/70

х = 2
