Question

The point 2, 3 lies on the graph of linear equation 3x - (A - 1)y=2a-1. If the same. Also lies on the graph of the linear equation 5 x + (1-2a) y=3b find the value of b.......tomm is my exam pls say tge answer

Answer 1

The point (2,3) is a solution of 3x-(a-1)y = 2a-1

Put x=2 and y=3 in given equation
3(2)-(a-1)*3 = 2a-1
= 6- 3a+3 = 2a-1
= 9-3a = 2a-1
= 5a= 10
a= 2

Point (2,3) also lies on
5x+(1-2a)y= 3b
Put x=2, y=3 and a=2

5(2)+(1-2(2))*3 = 3b
10+ (-3)*3 = 3b
10-9 =3b
b= 1/3
