Question

if X=2a-1 and Y=a-1 is a solution of the equation 2x-3y+5=0 find the value of a

Answer 1

2(2a-1)-3(a-1)+5=0
4a-2-3a+3+5=0
a=-6
hope helps....

Answer 2

Answer:

The value of a is -6.

Step-by-step explanation:

Given, x = 2a - 1 ;y = a - 1 is the solution of the equation, 2x-3y+5=0.

Putting the values of x and y in the given equation, 2x-3y+5=0;

2x-3y+5=0

⇒ 2 (2a - 1) - 3(a - 1) + 5 = 0

⇒ 4a -3a - 2 + 3 + 5 = 0

⇒ a + 6 = 0

⇒ a = -6.

Hence, the value of a is -6.
