Explain the answer I am good at geomtry but this question is littler hard for me the why i do it i get some wired answer? I will give u 10 points for the answer that explain it good and add up tp be 25 thanx.
Given BD (ray) bisects angle ABC
measure angle ABC = 25
solve for x and y.
There is angle ABC and BD (ray) divide it. there are two angles that make this up 1) angle ABD which is (2x - y) degrees and the other angle 2) is (3y - x) use the information above to solve this.

I may not have understood the problem exactly
I can guess that english is not your first language and all though your writing is a little confusing it is way better than my second language skill
I'm jealous of people who can communicate in a second language
if the problem is only that there are two angle that add up to 25 degrees and are described by the expressions given, then then are many solutions
add the two expressions and set them equal to 25 and solve
2x-y+3y-x=25
x+2y=25
2y=25-x
y=12.5-.5x
you can pick any x, say x=10, and calculate a y, that would be y=7.5
if I've done that right then that will add to 25
however, if the question implies that the angle is bisected "evenly" then there is only one solution, the one where each expression equals 12.5
that could be solved this way
2x-y=12.5
-x+3y=12.5
-2x+6y=25
5y=27.5
y=5.5
2x-5.5=12.5
2x=18
x=9
perhaps this helps
good luck

Since the ray bisects the angle, it cuts it into two equal peices. That means that ABD=DBC (or the other angle).
You write the equations out like this (2x-y)=(3y-x) and solve it for the different variables. (x=4y/3) and (y=3x/4)
maybe i'm just retarted...

It's possible to invest plenty of time and income looking for approaches to train your children how to see and boost their examining skills. Is difficult to teach a tiny child how to read, and even enticing them to learn is difficult in itself. But it does not have to be that way since you got the aid of this system https://tr.im/DrvNN , Children Learning Reading program.
With Children Learning Reading you will train your child how to split up sounds and separate phrases in to phonemes, an essential issue whenever your kid is merely learning how to spell.
The studying system from Children Learning Reading program makes it easy for kids to learn rapidly and effectively, from simple words to sentences till they understand to read stories.

How about you learn to speaky the english before you work on your little geometry homework. look into hooked on phonics, it could work for you.

Can't help you, sorry.
Friday was only my 2nd day of geometry.

(2x-y) + (3y-x) = 25
2x + (-y) + 3y + (-x) =25
x +2y =25
x=25-2y
y=12.5 -x/2
