Question

Solve for y when x=28 x+3y=28

Answer 1

Solving for y means to get that variable on one side of the equation and everything else needs to be on the opposite side of y.

We also know x is equal to 28. So, we can replace x with 28.
Now the equation will look something like 28 + 3y = 28

Now let us solve it.

28 + 3y = 28

First, subtract 28 from each side of the equation.

(28 + 3y) - 28 = 28 - 28 =
3y = 0

Now divide each side by 3.

3y / 3 = 0 / 3

y = 0/3

If a fraction has a numerator of 0, that means it's 0.

So, y is equal to 0.
