Question

For equation 3x - 4y = 16 if x = 8 then y = ?​

Answer 1

Answer:

If x=8, then 3(8)-4y = 16

24-4y = 16

24-16 = 4y

8 = 4y

y = 2

Answer 2

Given: 3x - 4y = 16 and x=8

To find The value of y

Solution: From the question, we can see an equation of two variables 'x' and 'y', and the value of x is provided to the question and we are told to find the value of 'y'. We will calculate it by putting the value of 'x' to the given equation

3x - 4y = 16 and then after performing the multiplication, addition, subtraction, and division operation, we can get the value of 'y'.

∴  3x - 4y = 16

⇒(3×8)-4y=16  [substituting the value of 'x']

⇒24-16=4y  [changing sides and thus changing the signs associated with that]

⇒4y=8

⇒y=8/4

⇒y=2

Hence the value of y is 2.
