Kenneth brings a partially-filled beaker of red liquid into is his laboratory and uses an apparatus to add drops of blue liquid to the beaker at a constant rate. The equation y = 5x + 15 describes the relationship between the number of minutes (x) since Kenneth began adding drops of blue liquid to the beaker and the total amount of liquid in the beaker (y), in milliliters. Which statement correctly describes a solution of the equation?

there are two ways you can do

[tex]y = 5x + 15 \\ \\ 1. \: y - 15 = 5x \\ 2. \: \frac{y - 15}{5} = x \\ 3. \: x = \frac{y - 15}{5} \\ \\ \\ 1. \: 5x + 15 = y \\ 2. \: 5x + 15 + - 15 = y + - 15 \\ 5x = y - 15 \\ 3. \: \frac{5x}{5} = \frac{y - 15}{5} \\ x = \frac{1}{5} y - 3[/tex]
