\[\huge~\rm~\bf~5x+6=2x+5 \]
this?
OpenStudy (anonymous):
yes
pooja195 (pooja195):
How would you approach the problem? What do you think you would do first?
OpenStudy (anonymous):
make plus to -
pooja195 (pooja195):

subtract 5 and 6 or bring 6 under 5 and then subtract
pooja195 (pooja195):
Good lets subtract 6 from both sides
\[\huge~\rm~\bf~5x+6-6=2x+5-6\]
What EQUATION are we left with once we do this?
OpenStudy (hyroko):
yup get X on one side and solve for X.
OpenStudy (anonymous):
1 then 0 and 0 , 4
pooja195 (pooja195):
Ok good :-)
5x=2x-1
Now what is the next step?

idk
pooja195 (pooja195):
We want to get x alone we would subtract 2x from both sides
5-2=?
OpenStudy (anonymous):
ok so 3 and then 0
pooja195 (pooja195):
good
3x=-1
divide both sides by 3 :-)
x= a fraction
x=-1/3
OpenStudy (anonymous):
so the answer is fraction
