Question 1127308
The sum of two numbers is 20. The difference between three times the first number and twice the second is 40. What are the two numbers ?
------
Equations::
x + y = 20
3x-2y = 40
-------
Solving by substitution::
x = 20-y
---
So, 3(20-y)-2y = 40
60-5y = 40
5y = 20
y = 4
-----
Then x = 20-y = 16
