Question

Решите уравнения:
(х - 17/15) + 5/8= 17/24
4 3/4 - (х - 2 5/8) = 3 5/6

Answer 1

(x-17/15)+5/8=17/24
x-17/15=17/24-5/8
x-17/15=17/24-15/24
x-17/15=1/12
x=17/15+1/12
x=68/60-5/60
x=63/60
x=21/20
x=1 1/20


4 3/4-(x-2 5/8)=3 5/6
x-2 5/8= 4 3/4-3 5/6
x-2 5/8= 19/4- 23/6
x-2 5/8=57/12-46/12
x-2 5/8= 11/12
x= 25/8+11/12
x= 75/24+22/24
x=97/24
x= 4 1/24
