Edna paid at least Php 1,200 for a pair of pants and a blouse.the cost of the pair of pants is Php600 more than cost of the blouse.

Sagot :

let the pants be x+600
and let the blouse be x
so the equation is
x+x+600=1200 or 2x+600=1200
transpose 600
so: 2x=1200-600
2x=600
now simplify (divide both by 2)
[tex] \frac{2x}{2} = \frac{600}{2} [/tex]
x=300
so the blouse is Php300
the pants are Php 900
(1200-600)/2=300+600=900
blouse=300
pair of pants=900
