Question

Solve for y.
py + qy = -4y +-8

Answer 1

`y=-8/[p+q+4]`

Explanation:

we have

`py+qy=-4y+(-8)`

`py+qy=-4y-8`

Solve for y

That means ----> isolate the variable y

Adds 4y both sides

`py+qy+4y=-4y-8+4y`

`py+qy+4y=-8`

Factor the variable y in the let side

`y[p+q+4]=-8`

Divide by (p+q+4) both sides

`y=-8/[p+q+4]`
