Question

Alice's age is 5 years less than 4 times her brother's age. Alice's age is 15 minus her brother's age. How old is Alice?​

Answer 1

Alice is 6 1/9

Explanation:

a is Alice and b is brother

a=4b-5

a=b-15

I prefer to use elimination

a=4b-5

-a=-b15

-3b=10

b=-10/3

a=4(10/3)-5

a=-55/3

Answer 2

6 1:9 oohgbsjdjjejnx
