Question

5•b-284-736
(13-а)+91=102
d-1301=254•117
9600:c=80•12
Помогите решить эти уравнения..
Умоляю вас!!!!

Answer 1

1) 5b - 284 - 736

5b - 102

2) (13 - a) + 91 = 102

13 - a + 91 = 102

104 - a = 102

- a = 102 - 104

- a = - 2

a = 2

3)d - 1301 = 254 * 117

d - 1301 = 29718

d = 29718 + 1301

d = 31019

4) 9600 / c = 80 * 12

9600/ c=80*12,c ne0

9600/c = 960

9600 = 960c

960c = 9600

c=10,c ne0

c = 10

Answer 2

2)
13-a=102-91
13-a=11
-a=11-13
-a=-2
a=2

3)
d-1301=29718
d=29718+1301
d=31019

4)

9600:c=960
c=960:9600
c=0,1

1) 5b-284-736
5b-1020
