Question

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

Answer 1

y = 8/p+q+4

Explanation:

Rearrange to get all y terms on one side.

py + qy + 4y = 8

Factorise py + qy + 4y

y(p + q + 4) = 8

Divide by p + q + 4 to solve for y

y = 8 / p + q + 4

Answer 2

y=8/(p+q+4)

Explanation:

py+qy=-4y+8

Collect all terms containing y together

Py+qy+4y=8

Factor out y

y(p+q+4)=8

Divide both sides by (p+q+4)

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

y=8/(p+q+4)
