If x and y are integers, Then how many possible equations can be formed for

5|X| + 2|Y| = 100.

• 4 equations are formed since mod function are defined in this way +x whenx>0 and -x when x

• Ans- 9 possible equ.
  
  5x18 +2x5 =100
  5x16 +2x10=100
  5x14 +2x15 =100
  5x12 +2x20=100
  5x10 +2x25=100
  5x8 +2x30 =100
  5x6 +2x35=100
  5x4 +2x40=100
  5x2 +2x45 =100
