Answer:

The first number is 5, and the other number is 12

Step-by-step explanation:

1st Number = n

2nd number = 2n +2

1st Number * 2nd Number =60

n(2n+2)=60

2n^2 + 2n =60

2n^2 +2n -60 = 0

Factor Out:

2(n-5)(n+6) = 0

n-5 = 0 n+6 = 0

n = 5 n = -6

n = -6 wont make sense so n =5 would be the answer

Check:

5(10+2) =60

5(12)= 60

60 = 60
