Question

Py+qy=-4y+8 what is the solution for y

Answer 1

Answer:

y=8/(P+q+4)

Step-by-step explanation:

we can find out that three items have y

so we can get them together Py+qy+4y=8

next(P+q+4)y=8   so y=8/(p+q+4)

Answer 2

Answer:

y = $\frac{8}{P+q+4}$

Step-by-step explanation:

Given

Py + qy = - 4y + 8 ← collect terms in y to the same side

Add 4y to both sides

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

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

y = $\frac{8}{P+q+4}$
