Question

In a number comprised of two digits, the the tens digit exceeds in 5 the unit digit. If we invert the order of the two digits, we have a new number. This new number added to the previous result in 121. ¿what is the number?

Please help

Answer 1

Let
x = units digit
y = tens digit
y = x + 5
x + 10y + y + 10x = 121
x + 10(x + 5) + x + 5 + 10x = 121
x + 10 x + 50 + x + 5 + 10x = 121
22x + 55 = 121
22x = 66
x = 3
y = 8
83
