Question

dateline weather the following system of linear equation had a unique solution x-2y=8 and 5x-10y= 10​

Answer 1

Answer:

For unique solution

a¹ /a² not equal to b¹/b²

By elimination method

first multiply x - 2y = 8 by 5 ,we get

5x - 10 y = 40

5x - 10y = 10

Add first and second equation

10 x = 50

x = 5

also by first equation

x = 8 +2y

5 = 8 + 2 y

y = 2/ 3

this is your answer

I hope this will help you
