Cd+e = 21    Equation

Cd + e - e = 21 - e  Subtract \ e \ from \ both \ sides

Cd = 21 - e    Simplify

Cd/C = 21-e/C  Divide \ both \ sides \ by \ C


d = 21-e/C.  Solution

Cd+e = 21

Cd + e - e = 21 - e

Cd = 21 - e

Cd/C = 21-e/C

d = 21-e/C.

24+3x=3x+3(7-1) What does x equal? Please show me how to do it I don't want the answer. (Well I do but show me how to get it als
balandron [24]

<span>                                               <u>24 + 3x = 3x + 3(7 - 1)</u>

Eliminate the parentheses:    24 + 3x = 3x + 3(6)

                                              24 + 3x = 3x + 18

Subtract  3x  from each side:       <em>24  =  18</em>

Look at that for a second.  Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."</span>
