C+ax=dx<br><br><br>this one has all variables and no numbers
sergeinik [125]
That's OK, but you have not said which variable you want to solve it for.

<u>To solve for 'x':</u>
                                           <span>c + ax = dx

Subtract c from each side:    ax = dx - c

Subtract  dx  from each side:   ax - dx = -c

Factor the left side:                 x (a - d) = -c

Divide each side by (a - d) :      x = -c / (a - d)  or  <u>x = c / (d - a)</u> .

</span><span><u>To solve for 'c': </u>
</span><span>                                   c + ax = dx

Subtract  ax  from each side and factor:   <u>c  = x (d - a) </u>

</span><u>To solve for 'd': </u>
                                      <span>c + ax = dx

Divide each side by 'x':     d = c/x + a .

<u>To solve for 'a':</u>
</span><span><span>                                           c + ax = dx</span>

Subtract 'c' from each side:    ax = dx - c

Divide each side by 'x':          <u>a = d - c/x </u>.
