The sum of two numbers 23, and their difference is 5.

Question

Write a system of linear equations and the resulting system. Let x be the larger number and y be the smaller number.

x+y=

Answer 1

14+9=23

14-9=5

Answer 2

X+y=23

x-y=5

add the equations

2x=28

x=14

thus

14+y=23

y=9

so-

x=14  y=9
