Question

5(1 – y)+4(1+ y) ÷1-2y=9
​

Answer 1

Answer:

the answer is 0

Step-by-step explanation:

5(1 – y)+4(1+ y) =9(1-2y)

5-5y+4+4y=9-18y

9-y=9-18y

-y-18y=-9+9

-19y=0

y=0

Answer 2

Answer:

y = 0

Step-by-step explanation:

$\frac{5(1 - y) + 4(1 +y)}{1 - 2y} = 9 \\ \\ \frac{5 - 5y + 4 + 4y}{1 - 2y} = 9 \\ \\ 9 - y = 9(1 - 2y) \\ 9 - y = 9 - 18y \\ - 18y + y = 9 - 9 \\ - 17y = 0 \\ y = \frac{0}{ - 17} \\ y = 0$
