Question

Which of the following pairs of linear equations are consistent/inconsistent? If
consistent, obtain the solution graphically:
(1) x + y= 5, 2 x + 2 y = 210 ​

Answer 1

Answer:

a1/a2 = 1/2, b1/b2 =1/2 , c1/c2 = 5/210= 1 /42

Step-by-step explanation:

here : a1/a2 = b1/b2 is not equal to c1 /c2

So it is inconsistent that it has no solution
