Answer:
c.2
Step-by-step explanation:
6x+18=h(3x+9)
To have an infinite number of solutions, the left and right side must be equal
Distribute the h
6x+18 = 3xh +9h
6x = 3xh
Divide by x
6x/x = 3xh/x
6 = 3h
Divide by 3
6/3 =3h/3
2 =h
Lets verify
18 = 9h
Divide by 9
18/9 = 9h/9
2 =h
h must be 2

Answer:
Elli's present age is 5 years and Peggy's present age is 15 years.
Step-by-step explanation:
Let Elli's present age be x
After 10 years Elli's age = x+10
Since we are given that Elli’s age in 10 years will be the same as Peggy’s age is now.
So, Peggy's present age = x+10
After 5 years
Elli's age will be x +5
Peggy's age = x+10 +5= x+15
Now we are given that Five years from now, Peggy’s age will be twice Elli’s age.
So,
So, Elli's present age = 5 years
Peggy's present age = x+10 =5+10 = 15 years
Thus Elli's present age is 5 years and Peggy's present age is 15 years.
