-t%22%22=%22%225

Indicate that the coefficient of t is -1:

red%28-1%29t%22%22=%22%225

Divide both sides by the coefficient of t which is red%28-1%29:

red%28-1%29t%2Fred%28-1%29%22%22=%22%225%2Fred%28-1%29

Cancel the red%28-1%29's on the left.

cross%28red%28-1%29%29t%2Fcross%28red%28-1%29%29%22%22=%22%225%2Fred%28-1%29

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

t%22%22=%22%22-5

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

Note that a shorter way is:

-t%22%22=%22%225

Chnage every sign on both sides

t%22%22=%22%22-5
