Each letter represents a non-zero digit. What is the value of ? Each letter represents a non-zero digit. What is the value of t? \begin{align*} c + o & = u, \\ u + n & = t, \\ t + c & = s, \\ o + n + s & = 12. \end{align*}
c + o= u u + n= t t + c = s o + n + s = 12
u+n=(c+o)+n=t
t+c=(c+o+n)=c=s
o+n+s=o+n+(c+o+n+c)=(c+o+n)*2+t*2=12 | divide by 2=
t=6
