Answer 2

Step-by-step explanation:

a 6x *1/6 =12*1/6.......dividing both side by 6

x = 2

b 7x-9+9 = 16 + 9 ........ adding both side by 9

7x = 25

7x * 1/7 = 25* 1/7 ........dividing both side by 7

x= 25/7

c y/1.5*1.5=1.6*1.5.......multiplying both side by 1.5

y = 1.6*10/1.5*10........multiplying and dividing

R.H.S by 10

y = 16/15

d 14y-8+8=13+8.........adding both side by 8

14y = 21

14y*1/14=21/14........dividing both side by 14

y = 21/14

Hence and.
