Question

Solve this system by rewriting the statements into a set of 2 equations. Then solve the equations using the addition method.The sum of two numbers is 18. The difference between the two numbers is 2. What are the two numbers?

Answer 1

x=first number
y=second number
let x>y

x+y=18
x-y=2
add both of the equation together to get
2x=20
x=10
since x-y=2,
y=8

FINAL ANSWER: 1st number: 10, 2nd number: 8
