Create a system of equations Janet is 5 years older than her brother David. The sum of their ages is 27. How old are Janet and David

Answer with steps please

Janet is 16, and David is 11.

Step-by-step explanation:

Let the ages be j and d.

j = d + 5

j + d = 27

Substitute d + 5 for j in the second equation.

d + 5 + d = 27

2d + 5 = 27

2d = 22

d = 11

Substitute 11 for d in the first equation.

j = d + 5

j = 11 + 5

j = 16

Janet is 16, and David is 11.
