Question 331334
<pre><b>

{{{-t}}}{{{""=""}}}{{{5}}}

Indicate that the coefficient of t is -1:

{{{red(-1)t}}}{{{""=""}}}{{{5}}}

Divide both sides by the coefficient of {{{t}}} which is {{{red(-1)}}}:

{{{red(-1)t/red(-1)}}}{{{""=""}}}{{{5/red(-1)}}}

Cancel the {{{red(-1)}}}'s on the left.

{{{cross(red(-1))t/cross(red(-1))}}}{{{""=""}}}{{{5/red(-1)}}}

Divide a positive five by a negative one, getting negative five:

{{{t}}}{{{""=""}}}{{{-5}}}

------------------------

Note that a shorter way is:

{{{-t}}}{{{""=""}}}{{{5}}}

Chnage every sign on both sides

{{{t}}}{{{""=""}}}{{{-5}}}
