Question

Three times one number added to another number is 39. Twice the first number minus the other is 6. What are the numbers?5

Answer 1

Explanation:

Answer 2

3x + y = 39 ........ (equation 1)
2x - y = 6 ............(equation 2)

By subtracting equation 1 - equation 2
5x = 45
Therefore, x = 45/5 = 9

To find y, substitute for x in equation 2
2(9) - y = 6
18 - y = 6
y = 18 - 6
y = 12

Therefore, the two numbers are 9 and 12.
