I will give you a medal! How can i solve linear equations in one variable?

pooja195 (pooja195):

\[\huge~\rm~\bf~5x+6=2x+5 \] 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):

Ok what are we going to subtract?

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

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

pooja195 (pooja195):

Correct the answer can also be a whole number

pooja195 (pooja195):

Do you understand how to do these?

OpenStudy (anonymous):

yes ty so much

pooja195 (pooja195):

Here are a few more examples |dw:1449890135347:dw| Yw ^_^
