Question

4 5/12 - 5 3/5x=2 2/3
5/18x + 2 1/2=10 5/6
решите уравнение

Answer 1

4 5/12-5 3/5х=2 2/3
5 3/5х= 4 5/12-2 2/3
5 3/5х= 4 5/12-2 8/12
5 3/5х=3 17/12-2 8/12
5 3/5х=1 9/12
5 3/5х= 1 3/4
х= 1 3/4: 5 3/5
х=7/4: 28/5
х=7/4* 5/28
х=5/16

5/18х+2 1/2=10 5/6
5/18х= 10 5/6-2 1/2
5/18х= 10 5/6-2 3/6
5/18х= 8 2/6
5/18х= 8 1/3
х= 8 1/3: 5/18
х= 25/3 :5/18
х=25/3* 18/5
х=30
