Question

Two times a number added to another number is 25. Three times the first number minus the other number is 20. Find the numbers.

Answer 1

first number is 9

second number is 7

Explanation:

2x + y = 25

3x - y = 20

Add the two equations so that 'y' is eliminated:

5x = 45

x = 9

2(9) + y = 25

18 + y = 25

y = 7
