Answer:
w = \frac{1 + y}{a + 2}
Step-by-step explanation:
collect the term in w together → ( subtract 2w from both sides)
y - aw - 2w = - 1 → ( subtract y from both sides)
- aw - 2w = - 1 - y → ( multiply through by (- 1) )
aw + 2w = 1 + y → ( take out w as a common factor )
w( a + 2)= 1 + y → ( divide both sides by (a + 2 ) )
w=\frac{1+y}{a+2}
