The sum of two numbers is 27. One number is 3 more than the other number. Write and solve a system of equations to find to two numbers

The first number is 12, the second is 15.

Step-by-step explanation:

One equation to solve this would be n + (n+3) = 27

n + (n+3) = 27

Simplified: 2n+3=27

2n+3=27

2n+3-3=27-3

2n=24

2n:2=24:2

n=12

When you plug n into the equation, you get 12 + (12+3) = 27

12 + (12+3) = 12+15

12+15=27

So, the first number is 12 and the second is 15
