The angles shown are
PR is the bisector of angle P
So
6/10 is the answer but if you want it simplified the the answer would be 3/5.
So you can use substitution...which is where you have Y all alone on one side of your equation and then plug it in to the other equation...2x-5=-3x+10 and you.solve for X. So x= 3. Then plug 3 into one of the original equations... Y=2(3)+5. So Y= 11.
Line 1 and line 4 are parallel
Step-by-step explanation:
Two lines are said to be parallel if they have same slope.
In order to compare the lines given, we have to write them all in the same form, and then compare their slopes.
Line 1:

Applying distributive property,

Line 2:

Line 3:

Applying distributive property,

Line 4:

re-arranging,

Now we have rewritten all the lines in the form
, where m is the slope. By comparing the values of m, we see:

Therefore, the lines which are parallel are line 1 and line 4.
