the sum of two numbers is 29 the difference between the same two numbers is 17.use a table to find the two numbers

Expert's answer

Let's denote two numbers as x,y

So we have

x+y=29&

x-y=17

Let's add two equations:

2x=29+17=46 whence x=23

y=29-x=29-23=6

the answer:& 23 and 6

So we have

x+y=29&

x-y=17

Let's add two equations:

2x=29+17=46 whence x=23

y=29-x=29-23=6

the answer:& 23 and 6
