Sando = Php 149
Pants = 287.80 pesos
Solution
x = sando
Equation:
x + (x + 45) + (x + 45 + 93.80) = 630.80
Add similar terms
3x + 183.80 = 630.80
Transpose
3x = 630.80 - 183.8
3x = 447
x = 149
The sando is Php 149 pesos
And since the pair of pants is 93.80 pesos more then the tshirt:
( 149 + 45 + 93.80)
= 287.80 pesos for pants
