Question 1205625
t, tens digit
u, the ones or units digit


If these are t for tens and t+4 for units
then {{{10(t+4)+1*t=10t+(t+4)+(3/4)(10t+t+4)}}}

{{{10t+40+t=10t+t+4+(3/4)(10t+t+4)}}}

{{{11t+40=11t+4+(3/4)(11t+4)}}}

{{{40-4=(3/4)(11t+4)}}}

{{{4*36=33t+12}}}

{{{33t=4*36-12}}}

{{{33t=132}}}

{{{3t=12}}}

{{{t=4}}}
