Question

Решите уравнение 2 15 * x + 45 = 1

Answer 1

2 1/5 • x + 4/5 = 1
2 1/5 • x = 1 - ( 4/5 )
2 1/5 • x = 1/5
X = 1/5 : 11/5
X = 1/11

Answer 2

2 1/5 • x + 4/5 = 1

Answer 3

2 15 *X =1 - 45=15

Answer 4

2 15 * x= 15

Answer 5

2 1/5*х+4/5=1
2 1/5*х=1-4/5
2 1/5*х=1/5
х=1/5:11/5
х=1/11

проверка
2 1/5*1/11+4/5=1
11/5*1/11+4/5=1
1/5+4/5=1
