You can put this solution on YOUR website! 16.8+3.2t=-13.6t
16.8+3.2t-3.2t=-13.6t-3.2t
16.8+0=-16.8t
16.8=-16.8t
16.8t/-16.8t=-16.8t/-16.8t
-1=t
Check, if t=-1 does the equation balance?
16.8+3.2(-1)=-13.6(-1)
16.8-3.2=13.6
13.6=13.6 Yes, so we know we're right!

If decimals make you lose your confidence, you can clear the decimals by multiplying everything by 10, but in this case it was easier to add and subtract decimals than to end up dividing a bigger number into a smaller number.
Happy Calculating!!!
