#t = 1.4#

Here's how I did it:

We know that in an equation, both sides equal each other, so anything done on one side must also be done on the other.

#-5t-2.2=-2.9#

The first thing we should do is add #2.2# to both sides of the equation:
#-5t - 2.2 + color(red)(2.2) = -2.9 + color(red)(2.2)#

#-5t = -0.7#

Now we divide both sides by #-5# :
#-5/color(red)(-5)t = -0.7/color(red)(-5)#

#t = 1.4#

Hope this helps!
