Question

3x-(a+1)y=2b-1 and 5x+(1-2a)y=3b find a ,b they coincide each other

Answer 1

Answer:

a=3-x-5y/7y

b=-1+2x+3ay+2y

Step-by-step explanation:

3x-(a+1)y=2b-1 ---> 1

5x+(1-2a)y=3b --->  2

subtracting equation 2 from 1

we will get

-2x-3ay-2y=-b-1 --> 3

then  we can get the value of b from equation 3

and then put the value of "b" in equation 1 or 2 we will be able to get the value of a
