Question

if linda = 2 linda + 1 , y = linda - 1 is a solution of the equation 2 linda - 3y +5 = 0 , find the value of linda

Answer 1

We have

$2x - 3y + 5 = 0$

It is given that x=2a+1 and a=a-1 is a solution of the equation 2x-3y+5=0

$2(2a + 1) - 3(a + 1)5 = 0$

$4a + 2 - 3a + 3 + 5 = 0$

$a + 10 = 0$

$a = - 10$
