Question

решите уравнения 1) x/9=12; 2) 286/y=13; 3) y+15/6=12

Answer 1

1) $\frac{x}{9} = 12$

12 * 9 =  x

x = 108

2) $\frac{286}{y} = 13$

13*y = 286

y = 286/13

y = 22

3) $\frac{ y+15}{6} = 12$ /*6

y + 15 = 72

y = 72 - 15

y = 57

Answer 2

1) х/9=12
х=12*9
х=108
2) 286/у=13
у=286/13
у=22
3) у+15/6=12
у+15=72
у=72-15
у=57
