graphically that the system of equations:2x + 4y = 10; 3x + y = 12 – InterviewSolution

1.

graphically that the system of equations:2x + 4y = 10; 3x + y = 12

Answer»

Given equations are 2x+4y=10 and 3x+6y=12

now in these two equations takea1 =2 and a2 = 3b1 = 4 and b2 = 6c1 =10 and c2 =12

by a1/a2 =2/3b1 /b2 = 4/6 =2/3c1/c2 = 10/12 =5/6

when a1/a2 = b1/b2 ≠c1/c2the two equations have no solution
