Question 762663
Simultaneous Equations:
5x + 3y = 2500...1
3x + 5y = 1900...2
Multiply (1) by 3
Multiply (2) by 5
15x + 9y  = 7500...3
15x + 25y = 9500...4
Subtract (3) from (4)
      16y = 2000
        y = 125
Substitute y = 125 into (1)
5x + 375 = 2500
       5x = 2500 - 375
       5x = 2125
        x = 425
Therefore a shirt costs P 425.00
          a tie costs P 125.00
Hope this helps.
