8t+21.2=17.3
Swap sides so that all variable terms are on the left hand side.
8t=17.3-21.2
Subtract 21.2 from both sides.
8t=-3.9
Subtract 21.2 from 17.3 to get -3.9.
t=\frac{-3.9}{8}
Divide both sides by 8.
t=\frac{-39}{80}
Expand \frac{-3.9}{8} by multiplying both numerator and the denominator by 10.
t=-\frac{39}{80}
Fraction \frac{-39}{80} can be rewritten as -\frac{39}{80} by extracting the negative sign.
