Answer:
17 and 10
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.
