Considering the question as
If two numbers are such that the sum of thrice the first and twice the second is 50 and four times the first exceed five times the second by 13. Find the numbers.
 
Let x and y be the numbers.
The sum of thrice the first and twice the second is 50.
The equation can be written as 3x + 2y = 50
Four times the first exceed five times the second by 13.
The equation can be written as 4x = 5y + 13.
 
3x + 2y = 50....(i)
4x - 5y = 13 ....(ii)
Solving these equations we get x = 12 and y = 7
