Answer 2

Answer:

x = 12/7

x= 127/13

x = 3/1350

x= -7

x= -8/15

Step-by-step explanation:

1:x/12 = 7

then, 12/x = 7 which becomes 12/7 = x

3:13 = 10-x

3/13 = 10-x

3 = 130 - 13x

130-3= 13 x

127/13 = x

3:15x =90

3/15x = 90

3= 1350 x

x = 3/1350

4:x+5 = -2

4/x+5 = -2

4= -2x-10

2x= -14

x = -7

5:2/3x = -4

5/2/3x = -4

(5*3x)/2 = -4

15x = -8

x = -8/15
