Question

Are the following pair of linear equations consistent? Justify your answer (1) -3x-4y=12 4y+3x=12

Answer 1

no

Step-by-step explanation:

-3x-4y=12

-7y=12

y=12/7

4x+3y=12

7y=12

y=12/7

Answer 2

Answer:

a1 = -3 ,b1= -4 , c2=-12

a2=3,b2=4,c2 =-12

a1/a2 = -1 ,b1 /b2 = -1 ,c1/c2 =1

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

hence ,the pair of linear equations have no solution,

so,they are inconsistent.
