What is 100% of the mass ?
Answer:
The first step should be adding 14 to both sides of the equation.
Step-by-step explanation:
14 must be added on both sides of the equation to get 13y by itself. The ultimate goal is to get y by itself if we are solving for y.
Once 14 is added on both sides, you'll get:
13y = 56.
Then 13 would be divided from both sides.
y = 4.3
