Answer:
10 and 7
Step-by-step explanation:
Let the numbers be A and B
The sum of the two numbers is 17.
That’s
A + B = 17
The difference of the numbers is 3
A - B = 3
We now have two equations
1. A + B = 17
2 . A - B = 3
Subtract equation two from equation one.
B - - B = B + B = 2B
2B = 14
Divide both sides by 2
2B/2 = 14/2
B = 7
Now substitute 7 for B into either of the equations to get A.
Using equation 1 we have
A + B = 17
A + 7 = 17
Subtract 7 from both sides
A - 7 = 17 - 7
A = 10
The numbers are 10 and 7
