6.4-2.7t=18.9
Swap sides so that all variable terms are on the left hand side.
-2.7t=18.9-6.4
Subtract 6.4 from both sides.
-2.7t=12.5
Subtract 6.4 from 18.9 to get 12.5.
t=\frac{12.5}{-2.7}
Divide both sides by -2.7.
t=\frac{125}{-27}
Expand \frac{12.5}{-2.7} by multiplying both numerator and the denominator by 10.
t=-\frac{125}{27}
Fraction \frac{125}{-27} can be rewritten as -\frac{125}{27} by extracting the negative sign.
