18. Solve the problem by writing a system of equations in two variables and then solving it. The sum of two numbers is 17. If the larger n
Let L = larger number and S = smaller number
L + S = 17 The sum of the two numbers is 17.
L = 2 + 2S The larger number is two more than twice the smaller.
Substitute the value of L from the second equation into the first equation:
(2 + 2S) + S = 17
2 + 3S = 17
3S = 15
S = 5
L = 12
