Consecutive numbers whose sum is 438.

i did x+1x+2x
3x+1=438
3x= 438 - 1
3x= 437
x= 437 divided by 3
x= 145, 146 and 147

is it right?

3 consecutive integers
you messed up on first step
you got the x, x+1, x+2 part right
then you did this: 3x+1=438
you should have done: 3x+3=438
then minus 3
3x=435
divide by 3
x=145
then
x+1=146
x+2=147

numbers are 145,146,147
to check, you could have found the numbers and seen if they added to 438

What am i doing here. add?
