(you may mean: solve for "u")
Answer: [tex]t=u^2-v[/tex]
Step-by-step explanation:
[tex]v=u^2-t[/tex]
[tex]\mathrm{Add\:}t\mathrm{\:to\:both\:sides}:[/tex]
[tex]v+t=u^2-t+t[/tex]
[tex]\mathrm{Simplify}[/tex]:
[tex]v+t=u^2[/tex]
[tex]\mathrm{Subtract\:}v\mathrm{\:from\:both\:sides}:[/tex]
[tex]v+t-v=u^2-v[/tex]
[tex]\mathrm{Simplify}:[/tex]
[tex]t=u^2-v < -answer~;3[/tex]
