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
