First,B bisects AC, this means that B dovids AC into two equal halves. therefore AB=AC
second and third steps are just isolating the terms containg y on one side of the equation and the other terms on the other side.
finally you have 3y=15, to get the value of y,you divide both sides of the equation by 3.

Elias and Niko are polishing the silver at the heritage museum.Elias could polish all the silver himself in 40 minutes.That task

Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make $\frac{1}{40}$ of the total work. If the same analysis is applied Niko, in 1 minute, will make $\frac{1}{50}$ of the total work.

Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make $\frac{1}{x}$ of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:
