Question

Помагите решить уравнения 31-6x=5-20x 9-7x=5x+37

Answer 1

31-6х=5-20х
20х-6х=5-31
14х=-26
х=-26:14
х=-1 12/14=-1 6/7

9-7х=5х+37
7х+5х=9-37
12х=-28
х=-28:12
х=-2 4/12=-2 1/3

Answer 2

31-6х=5-20х
20х-6х=5-31
14х=-26
х=-26/14
х=-1 12/14=-1 6/7

9-7х=5х+37
5х+7х=9-37
12х=-28
х=-28/12
х=-2 4/12=-2 1/3
