is 4. Find the numbers.​

Answer 1

Answer:

x+y=6

x-y=4

2x=10

x=5

y=1

Answer 2

Answer:

The first number is 5, and the second number is 1.  

Step-by-step explanation:

x = first number

y = second number

x + y = 6

x - y = 4

Isolate the variable x in the first equation and plug it into the second equation.

x = 6 - y

6 - y - y = 4

6 - 2y = 4

-2y = -2

y = 1

Plug y back into the first equation to find x.

x + 1 = 6

x = 5

Check!

If x = 5 and y = 1,

5 + 1 = 6

5 - 1 = 4
