GI bisects with DGH so that m DGI is x-3 and m IGH is 2x-13 . Find the value of x.
HELP!

Since GI bisects angle DGH, this means that angles DGI and IGH are congruent
jimthompson5910 (jim_thompson5910):
so
DGI = IGH
x-3 =2x-13
OpenStudy (anonymous):
so what does x equal.. lol
jimthompson5910 (jim_thompson5910):
solve for x and tell me what you get
OpenStudy (anonymous):
idk how..

Start by adding 3 to both sides
OpenStudy (anonymous):
add 3 to what..?
jimthompson5910 (jim_thompson5910):
x-3 =2x-13
x-3+3 =2x-13+3 .. Add 3 to both sides.
x = 2x-10
jimthompson5910 (jim_thompson5910):
then what?
OpenStudy (anonymous):
that makes no sence..

alright, let me find a few pages on solving linear equations
OpenStudy (anonymous):
ugh
jimthompson5910 (jim_thompson5910):
the basic idea is to isolate x
you do this by moving all the x terms to one side and all the non x terms to the other
OpenStudy (anonymous):
so do you know the answer..

i do, but I want to help you get it and not just give you the answer
OpenStudy (anonymous):
okay so what do i do now?
jimthompson5910 (jim_thompson5910):
The next step is to subtract 2x from both sides
jimthompson5910 (jim_thompson5910):
x = 2x-10
x-2x = 2x-10 - 2x
-x = -10
then what?
OpenStudy (anonymous):
uh.. i have no idea..

add x? idkk.. /:
jimthompson5910 (jim_thompson5910):
if -x = -22 for example, then x = 22
OpenStudy (anonymous):
so it equals 10?
jimthompson5910 (jim_thompson5910):
you got it, x = 10
OpenStudy (anonymous):
so thats the answer?
