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

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