Question 373381
you have to solve for the individual digits ___ let t=tens digit and u=units digit


"The sum of a two-digit number is 11" ___ t + u = 11


"The difference between the number and the number with its digits reversed is 27" ___ 10t + u + 27 = 10u + t


9t + 27 = 9u ___ t + 3 = u


substituting ___ t + (t + 3) = 11 ___ t = 4


substituting ___ (4) + u = 11 ___ u = 7
