Question

If x = 2 α + 1 and y = α -1 is a solution of the equation 2x – 3y + 5 = 0, find the value of α

Answer 1

Answer:

this is the perfect solution for this question mark me as the brainliest

Answer 2

x = 2 - α and y = 2 + α is a solution of 3x - 2y +6 = 0

3 x – 2 y + 6 = 0

⇒ 3 (2 - α) - 2 (2 + α) + 6 = 0

⇒ 6 - 3α - 4 - 2α + 6 = 0

⇒ -5α + 8 = 0

⇒ -5α = -8

a= 8/5
