Question

Solve for y. Assume the equation has a solution for y. py + qy = -4y + 8

Answer 1

y =
`(8)/(p+q+4)`

Explanation:

py + qy = - 4y + 8 ( add 4y to both sides )

py + qy + 4y = 8 ← factor out y from each term on the left side

y(p + q + 4) = 8 ← divide both sides by p + q + 4

y =
`(8)/(p+q+4)`
