Answer:
x = 111
Step-by-step explanation:
1.) x + (x + 1) + (x + 2) = 336
2.) x + x + 1 + x + 2 = 336
3.) 3x + 3 = 336
4.) 3x = 333
4.) x = 111
Check Work:
1.) 111 + (111 + 1) + (111 +2) = 336
2.) 111 + 111 + 1 + 111 + 2 = 336
3. ) 222 + 1 + 111 + 2 = 336
4.) 222 + 114 = 336
5.) 336 = 336
Answer:

Answer:
The numbers are 2 and 7.
Step-by-step explanation:
If x and y are the 2 numbers:
x + y = 9
x - y = 5 Adding the 2 equations
2x + 0 = 14
x = 7.
Plug this into the first equation:
7 + y = 9
y = 2.
