Ah I love consecutive problems, so we have three this time, thinking about what we did last time what do you think it will look like if you start the equation as
\[114=\]

use the equation \[144=x+x+1+x+2\]
OpenStudy (notamathgenius):
144= 3x+1+2
satellite73 (satellite73):
if you are in college, then you should be able to "think" i.e suss out a problem without being a slave to some method
you will learn something as you do it
OpenStudy (benji):
Yep now solve for x and thats the youngest
satellite73 (satellite73):

114******
satellite73 (satellite73):
which is why i guessed \[32+33+34\] but it didn't work, so try \[34+35+36\] and see if that one does
OpenStudy (notamathgenius):
its 105
OpenStudy (benji):
114-3 = 111/3=?
