Step-by-step explanation:

4y+3x=-3y=5x-5

| Take the derivate of each term, with respect y

d/dy (4y+3x=-3) = d/dy (5x)- d/dy (5)

| The derivate of a constant is always 0

d/dy (4y+3x=-3y) = d/dy (5x) - 0

| When adding or subtracting 0, the quantity does not change

d/dy(4y+3x=-3y)= d/dy (5x) : Using the Chain rule

d/dy(5x) = d/dx (5x) x dx/dy, take the divate
