Question

write the number of solution of the pair of linear equations x+3y-4=0 and 2x+ 6y=7 ​

Answer 1

Answer: There is no solution

Step-by-step explanation:

=》x+3y-4=0;

2x+6y=7 =》2x+6y-7=0

a1/a2=b1/b2=c1/c2

a1=x, a2=2x, b1=3y, b2=6y, c1=-4, c2-7

=》x/2x= 3y/6y= -4/-7

Now 3y and 6y cancel and -4 and -7 minus cancel

=》 1/2=1/2 not equal to 4/7

The number of solution is no solution

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