Step-by-step explanation:
4x−5y=6
−8x+10y=−12
Isolate x for 4x –5y = 6: x=6-5y/4
Substitute x= 6+5y/4
[-8 (6-5y/4) +10y=-12]
Simplify
[-12= -12 ]
The solutions to the system of equations are:
x=6+5y/4
Answer:
The answer is
Step-by-step explanation:
Solution:
Let we first name the Triangle as Δ ABC and ray BD as a bisector of ∠B
as shown in the figure below.
As ray BD is the bisector of angle B so, by Angle bisector theorem property we have
∴
∴
∴
∴ final answer
