Givens

There are 3 sides. All are equal to (4x - 3)

Their sum = 63

Formula

3(4x - 3) = 63

Solution

  • 3(4x - 3) = 63            Divide by 3
  • 12x - 9 = 63               Add 9 to both sides
  • 12x = 63 + 9    
  • 12x = 72                    Divide by 12
  • x = 72/12

x = 6                          Answer
