Question

Solve for x
d(-3+x)=kx+9

Answer 1

x =
`(9+3d)/(d-k)`

Explanation:

Given

d(- 3 + x) = kx + 9 ← distribute parenthesis on left side

- 3d + dx = kx + 9 ( add 3d to both sides )

dx = kx + 9 + 3d ( subtract kx from both sides )

dx - kx = 9 + 3d ← factor out x from each term on the left side

x(d - k) = 9 + 3d ← divide both sides by (d - k)

x =
`(9+3d)/(d-k)`

Answer 2

x=3(3+d)/ d-k

Hope this helps:)
