we are given
we can multiply -1 on both sides of second equation
we can see that
both equations becomes same
so, they are coincident............Answer

Answer:
The decimal number system in use today was first recorded in Indian mathematics.
Step-by-step explanation:
In the classical period of Indian mathematics (400 AD to 1200 AD), important contributions were made by scholars like Aryabhata, Brahmagupta, Bhaskara II, and Varāhamihira. The decimal number system in use today was first recorded in Indian mathematics.
1)y=3x
2)y=x
3)y=7x
4)y=x+7
4)y=2x+1
6)y=12x+2
