x+x+1+x+2 = -15

3x+3=-15

3x=-18

x=-6

7) let the number be x

2x=22

x=11

Answer 2

Step-by-step explanation:

(iv):- let the number be *x*

now ,

x/2+x/10=60

5x/10+x/10=60

6x/10=60

x=60*10/6

x=100

(v):- let the number be:-

x , x+1 , x+2

x+x+1+x+2=(-15)

3x+3=(-15)

x+1=(-15)/3

x+1= -5
