Group our variables 5t and 6.5t subtract 6.5t from both sides 5t + 20 - 6.5t = 6.5t - 6.5t
Cancel 6.5t on the right side:
-1.5t + 20 = 0
Group constants
Group our constants 20 and 0. subtract 20 from both sides -1.5t + 20 - 20 = 0 - 20
Cancel 20 on the left side:
-1.5t = -20
Divide each side of the equation by -1.5
-1.5t
-1.5
=
-20
-1.5
t = 13.333333333333
Final Answer
t = 13.333333333333
What is the Answer?
t = 13.333333333333
