A number 54 divide into 2 parts so that 10 times the 1st and 22 times 2nd are together equal to 780 the difference of the parts

• let the numbers are x and 54-x.
  now 10x+22(54-x)=780
  10x+1188-22x=780
  x = 34
  so 1st part = 34 and 2nd part = 20.
  thus difference of the parts = 34-20 = 14

• let the numbers are a and 54-a.
  now 10(54-a)+22*a=780
  a=20
  54-a = 34
  so, difference of the parts = 34-20 = 14
