Answer 1

Step-by-step explanation:

REPLACEMENT SET IS A

-4,-3,-2,-1,0,1,2,3

3Y-6<-4

3Y=-4<-6 (digits will be changed)

-+-=+ so, 3y=<4+6>

3y=<4+6> = the right answer

2nd question

2(p-9)/7+p/3=3

Lcm of 7 and 3=21

So 2(p-9)×21/7×3+p×3/3×7=3

So p=x

2x-9×21/21+p×3/21=3

2x-189/21+3p/21=3

So,x= 189-2/21+3p/21=3

X=187/21+3p/21=3

Divide 187/21 =8.904761

8.904761+3p/21=3

11.904761/21=3

0.5668933809523=3

Linear equation =0.5668933809523=3
