Answer:

y=0

Step-by-step explanation:

If x equals 28 then substitute it in the equation, 28+3y=28

Next, subtract 28 from both sides, 3y=0

Now that you have that its simple, y must equal 0

Answer:

y = 0

Step-by-step explanation:

We are given the following equation and we are to find the value of y when x equals to 28:

[tex] x + 3y = 28 [/tex]

Substituting the given value of x in the above equation:

[tex] 28 + 3y = 28 [/tex]

[tex] 3y = 28 - 28 [/tex]

[tex] 3y = 0 [/tex]

[tex] y = \frac{0}{3} [/tex]

[tex] y = 0 [/tex]

Therefore, y = 0 when x = 28.
