Question

For an equation 2x – 5y = 1, if x = 3 then then y = ?​

Answer 1

Solution:

On substituting x with 3, we get,

2x - 5y = 1

as

2(3) - 5y = 1

⇒ 6 - 5y = 1

⇒ -5y = 1 - 6

⇒ -5y = -5

⇒ 5y = 5     [multiply both side with (-1)]

⇒ y = 5/5 = 1

Answer:

y = 1

Answer 2

Step-by-step explanation:

2x - 5y = 1

2(3) -5y = 1

6 - 5y = 1

6 - 1 = 5y

1 = 5y

y =5/5

y = 1
