Question

The equation 5x + (–2y) = 8 relates the amount spent, y, to the number of picture frames purchased, x, after a discount for buying two or more frames is applied to the total cost of the frames. How much is the discount?
GPT 3.5
To find the discount, we need to isolate the y variable in the equation.

Starting with the given equation: 5x + (-2y) = 8

Rearranging the terms: -2y = 8 - 5x

Dividing both sides by -2: y = (8 - 5x) / -2

Therefore, the discount is the value of (8 - 5x) / 2.
