Question

For what values of a and b does the pair of linear equations have number of solutions 2x-3y=7, ax+3y=b​

Answer 1

Answer:

a= -2 b= 7

Step-by-step explanation:

two pairs of linear eq have infinite number of solutions when a1 /a2=b1/b2=c1/c2 therefore here b1/b2=-1 so to make a1/a2 =-1 a is -2 similarly b=7

actually they are single line only that is why they have infinite solutions
