Question

What is the value of the expression when y = 2? StartFraction 2 minus y Over 4 plus y EndFraction plus StartFraction 3 (y plus 2) Over y EndFraction 3One-half 6 6One-sixth 12

Answer 1

The answer is 6

How you get this answer is by plugging in the number 2 in as y and following the order of operations.

Answer 2

6

Explanation:

Given the expression
`(2-y)/(4+y) + (3(y+2))/(y)`, we are to look for the value of the expression when y = 2. To do that we are going to substitute y as 2 into the given expression and simplify the resulting expression as shown.

`f(y) = (2-y)/(4+y) + (3(y+2))/(y)\\\\if \ y = 2;\\\\f(2) = (2-2)/(4+2) + (3(2+2))/(2)\\\\f(2) = (0)/(6) + (3(4))/(2)\\\\\\f(2) =0 + (12)/(2)\\\\\\f(2) = 6`

Hence the value of the expression when y = 2 is 6
