Question

решите уравнение 1) 7 3/10+25/28x=8 13/35 2)3/8x+7/12x-5/6x=9/32

Answer 1

7 3/10+25/28x=8 13/35
25/28x=8 13/35-7 3/10
25/28x=8 26/70-7 21/70
25/28x=1 5/70
25/28x=1 1/14
x=15/14:25/28
x=15•28/14•25
x=6/5
x=1 1/5
Ответ: 1 1/5

3/8x+7/12x-5/6x=9/32
9/24x+14/24x-20/24x=9/32
23/24x-20/24x=9/32
3/24x=9/32
1/8x=9/32
x=9/32:1/8
x=9•8/32
x=9/4
x=2 1/4
Ответ: 2 1/4
