Question

make w the subject of the formula y-aw=2w-1

Answer 1

w = $\frac{1 + y}{a + 2}$

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 = $\frac{1 + y}{a + 2}$

Answer 2

w( a + 2)= 1 + y → ( divide both sides by (a + 2 ) )

w = \frac{1 + y}{a + 2}
