the sum of two numbers is 27. the larger number is 3 more than the smaller number. what are the two numbers?

Question

it is for algebra one. and you are supposed to show the equation and you are supposed to do in a certain order

Answer 1

Let x = the smaller number

Let y = the larger number

 

x + y = 27

y = x + 3     Using substitution, replace y in the first equation with x + 3.

x + x + 3 = 27

2x + 3 = 27

2x = 24

x = 12

y = 12 + 3

y = 15
