Question

Check whether 3x-5y+4=0,4x+10y=14 is consistent or inconsistent,if consistent then solve for x and y

Answer 1

Answer:

consistent

Step-by-step explanation:

3x-5y=-4........eq(1)

4x+10y=14......eq(2)

eq(1)*4

eq(2)*3

eq(1)-(2)

12x-20y=-16

12x+30y=42

-50y=-58

y=58/50

sub in eq(1)

3x-5(58/50)=-4

3x-5.8=-4

3x=-4+5.8

3x=1.8

x=1.8/3

x=0.6
