Question

Three times one number minus a second is 8 and the sum of the number is 12

Answer 1

one number is 2

second number if 3 1/3

Explanation:

a = one number

b = second number

3a - b = 8

3a + b = 12

add together:

6a = 20

a = 20/6 or 10/3

find 'b':

3(10/3) - b = 8

10 - b = 8

-b = -2

b = 2
