We want to eliminate the variable y. What number should we multiply times the first
equation, so that when we add the two equations, we can eliminate the variable y?

Answer 1

Delta does not have a relative extreme in the equation, so it is variable y It can not be true

Explanation:

`s = 5x + 3y`

There is an answer

The rest of the equation that has no substituted delta is not true, so the prime variables have relative extremes.
