Answer:
y=x+w/5
Step-by-step explanation:
x=5y-w
step 1: bring the additional letters/numbers next to the "5y" over to the left
x+w= 5y
step 2: divide the numbers and letters on both sides of the "=" by 5 to only get the letter y
x+w/5= y
step 3: swap them over
y= x+w/5
(we can't get an answer from x+w/5 because the terms are unlike, therefore we keep it as a fraction

A fraction is in
simplest form
when no other factor but 1 will divide into the numerator/denominator.
We can write an equation to solve this:
Let x represent amount of Blue Jays.
2x + x = 21
We can simplify the equation:
3x = 21
Divide both sides by 3 to isolate x variable:
x = 7
Therefore, 7 Blue Jays.
