Answer:

17 and 10

Step-by-step explanation:

Write the problem as an equation.

a+b=27

a=b-7

Where a and b are the two numbers you are trying to find. You could use any variables. Then solve.

b+(b-7)=27      Sub (b-7) for a

2b-7=27          Group like terms

2b=34             Add 7 to both sides

b=17                 Divide both sides by 2.

Because b=17, a must be 10.
