Question 441228: The sum of two numbers is 50. Two times the first number is ten more than the second. Find the two numbers. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let one number be x & the other y
1 x + 1 y = 50 .............1
2 x + -1 y = 10 .............2
Add the two equations
3 x = 60
/ 3
x = 20
plug value of x in (1)
1 x + 1 y = 50
20 + 1 y = 50
1 y = 50 -20
1 y = 30
y = 30
