How do you solve #38.8 - 9 . 7 t = - 6 7 . 9#?

1 Answer

Solving for #t# gives an answer of #11#.

Explanation:

First, you gather LIKE TERMS on each side of the equation, so for this question, we'll put everything with a #t# on the left side, and everything without a #t# on the right:

#-9.7t = -67.9-38.8#

Then we simplify each side (the left already is):

#-9.7t = 106.7#

Now, we want #t# all by itself, so since it is multiplied by #-9.7#, we will divide both sides by #-9.7# (because you always have to do the same thing to each side of an equation to KEEP it equal)

#(-9.7t)/-9.7 = 106.7/-9.7#

#t = 11#
