Question

8y + 9 by 2 = 4y by 9​

Answer 1

Answer:

$\frac{8y + 9}{2} = \frac{4y}{9} \\ \\ 9(8y + 9) = 2 \times 4y \\ 72y + 81 = 8y \\ 72y - 8y = (- 81 )\\ 64y = (- 81) \\ y = \frac{ - 81}{64}$

Answer 2

Answer:

-81/64

Step-by-step explanation:

8y + 9/2 = 4y/9

9(8y + 9) = 2(4y)

72y + 81 = 8y

72y - 8y = -81

64y = -81

y = -81/64

∴ the value of Y is -81/64
