Question

Consider the equation `y = 2 - 3x`. If `y = 11`, what is `x`?

Answer 1

`x=3`

Explanation:

To solve for `x` first substitute the given value of `y` into the given equation:
`11 = 2 - 3 * x`

Then subtract `2` from both sides
`11 - 2 = ( 2 - 3 x ) - 2 rarr 9 = 3 x`

Finally divide both sides by `3`, we get
`9/3 = (3x) / 3 rarr 3 = x`
