Any two-digit number have a digit at one's place and at ten's place. lfwe consider digit at ten's place as 'x' and digit at one's place as 'y' then, a two-digit number is written in the form of an algebraic expression is shown as:
10x+y
The linear equation representing the situation. The tens digit is three times the unit digit is".
