Cy+4=d-9y solve for y

y = (d - 4) / (C + 9)

Step-by-step explanation:

Cy + 4 = d - 9y

Cy + 9y = d - 4

y (C + 9) = d - 4

y = (d - 4) / (C + 9)

y = d-4 / c+9

Step-by-step explanation:

cy+4=d-9y

Step 1: Add 9y to both sides.

cy+4+9y=d-9y+9y

cy+9y+4=d

Step 2: Add - 4 to both sides.

cy+9y+4+-4=d+-4

cy+9y=d-4

Step 3: Factor out variable y.

y (c+9) = d-4

Step 4: Divide both sides by c+9.

y (c+9) c+9 = d-4 / c+9

y = d-4 / c+9
