1. Write the equation:
d(-3 + x) = kx + 9
2. "Open" the parenthesizes:
-3d + dx = kx + 9
3. Take kx to the left side, -3d to the right, everything with different sign (+ replace with - when transferring, - replace with +):
dx - kx = 9 + 3d
4. Factor x in the left side:
x(d - k) = 9 + 3d
5. Finally, divide the whole equation by (d - k):
x = (9 + 3d)/(d - k)
That's the final answer. Good luck!

Solving for x in the given equation; x =(9+3d)/(d-k)

Solving for x

The given equation is;

  • d(-3+x)= kx+9

By expansion;

  • -3d +dx = kx +9

  • x(d-k) = 9+3d

Divide both sides of the equation by (d-k);

  • x = (9+3d)/(d-k)
