Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line
Answer:
x=1 y=3
Step-by-step explanation:
3x+y=6 is the same as y=6-3x
2x-y=-1 is the same as y=2x+1
set them equal to each other
6-3x=2x+1
5x=5
x=1
substitute the value of x into either equation
y=2(1) +1
y=3
