Answer:

x = -9 / (2d+k)

Step-by-step explanation:

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

-3dx + dx = kx+9

-3dx + dx - kx = 9

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

x (-2d-k)= 9

x [-(2d+k)]=9

x = -9 / (2d+k)

Answer:

The value of the provide equation for x is [tex]x=\frac{9+3d}{d-k}[/tex].

Step-by-step explanation:

Consider the provided equation.

[tex]d(-3+x)=kx+9[/tex]

We need to solve the equation for x.

Use the distributive property: [tex]a(b+c)=ab+ac[/tex]

[tex]-3d+xd=kx+9[/tex]

Subtract kx from both sides.

[tex]-3d+xd-kx=kx-kx+9[/tex]

[tex]-3d+xd-kx=9[/tex]

Add 3d both sides.

[tex]-3d+3d+xd-kx=9+3d[/tex]

[tex]xd-kx=9+3d[/tex]

Take x common from left side.

[tex]x(d-k)=9+3d[/tex]

Divide both the sides by d-k.

[tex]\frac{x(d-k)}{d-k}=\frac{9+3d}{d-k}[/tex]

[tex]x=\frac{9+3d}{d-k}[/tex]

Hence, the value of the provide equation for x  is [tex]x=\frac{9+3d}{d-k}[/tex].
