Answer:
x = 5
Step-by-step explanation:
The angle bisector divides the sides proportionally.
(2x -1)/9 = 3x/15
5(2x -1) = 3(3x) . . . . . . multiply by 45
10x -5 = 9x . . . . . . . . . eliminate parentheses
x = 5 . . . . . . . . . . . . . . add 5-9x
It should be multiplied by the opposite of the coefficient of y in the first equation, hence
B)) -2
_____
Actually, it depends on your choice of next step. Multiplying by -2 lets you add the two equations. Multiplying by 2 means you need to subtract one equation from the other. We usually find addition easier, so we would usually choose -2, but either can work. It depends on whether you like to add negative numbers or subtract positive ones.

Answer:
I believe its m > -6
Step-by-step explanation:
if I'm wrong I'm really sorry...
1.-x[6+(4*2)]-5, first do the things in the parenthesis: 4*2=8, then +6=14 then *-x=-14x and keep the -5
-14x-5
