Question

8x-7x+10=13 3g-g+16=32 525:k=82+23 148-13y=85

Answer 1

8х - 7х + 10 = 13

1х = 13 - 10

х = 3

3g - g + 16 = 32

2g = 32 - 16

2g = 16

g = 16 : 2

g = 8

525 : k = 82 + 23

525 : k = 105

k = 525 : 105

k = 5

148 - 13у = 85

13у = 148 - 85

13у = 63

у = 63/13

у = 4 целых 11/13

Answer 2

$8x - 7x + 10 = 13 \ x + 10 = 13 \ x = 13 - 10 \ x = 3 \ \ 3g - g + 16 = 32 \ 2g + 16 = 32 \ 2g = 32 - 16 \ 2g = 16 \ g = 8 \ \ 525 div k = 82 + 23 \ frac{525}{k} = 105 \ \ 525 = 105k \ 105k = 525 \ \ k = 5 \ 148 - 13y = 85 \ \ - 13 = 85 - 148 \ \ - 13y = - 63 \ \ y = 4 frac{11}{13}$
