Respuesta :
You have to combine like terms. Add 20 to -20 and add 20 to 30, (So 50t+25=1000). Subtract 25 from 1000, (50t=975). Divide 975 by 50, (19.5). And 50t by 50. And you should get t=19.5 . I might be wrong though.
The answer is
[tex] t = \frac{39}{2} [/tex]
or
[tex]t = 19 \frac{1}{2} \: simplified[/tex]
[tex] t = \frac{39}{2} [/tex]
