Question

Solve the equation. 4d + 2d – 4d + 4 = 3d

Answer 1

d = 4

Explanation:

1. Simplify both sides of this equation, to start off with.

`4d+2d−4d+4=3d</strong></p><p><strong>[tex]4d+2d−4d+4=3d`

`4d+2d+−4d+4=3d`

2. Combine all the like terms you see here.

(4d+2d+−4d)+(4)=

d+4=3d[/tex]

(2d+4=3d)[/tex]

3. Subtract 3d from both sides of this equation.

`2d+4−3d=3d−3d`

`- d + 4 = 0`

4. Subtract 4 from each sides of the equation.

`−d+4−4=0−4`

`- d = - 4`

5. Divide both of the sides by -1.

`( - d)/( - 1) = ( - 4)/( - 1)`

Therefore, the answer is d = 4.
