Let T = the ten's digit
Let U = the unit's digit
Given: ten's digit is 1 MORE than 4 TIMES the units digit -> T = 1 + 4U
Given: sum of the digits is 6 -> T + U = 6
Substitute the value for T in the 1st equation and substitute in the 2nd:
1 + 4U + U = 6
5U = 5
U = 1
So the ten's digit is 1 + 4*1 = 5
The number is 51
