Question

find the value of a and b for the
following pair of linear equation has infenety many solution

(a-1)x+3y=2
6x +( 1-2b)y =6​

Answer 1

Answer:

(a=3) & (b= (-4)}

Step-by-step explanation:

for infinitely many solution:-

a¹/a²=b¹/b²=c¹/c²

so, (a-1)/6=2/6

=>a-1=2

=>a=3

and, 3/(1-2b)=2/6

=>1-2b=(6*3)/2

=>1-2b=9

=>-8=2b

=>-4=b
