Question

Harga baju sama dengan 3 kaos.harga baju dan 2 kaos RP 76.000.harga baju?

Answer 1

Misalkan baju = x kaos = y
Maka didapat persamaan :
x= 3y
x + 2y = 76000

3y + 2y = 76000
5y = 76000
y = 15200
x = 3( 15200 )
x = 45600

Harga baju = Rp.45600

Answer 2

Kita umpamakan:
Baju = x
Kaos = y
x = 3y
"harga baju dan 2 kaos = 76K"
x + 2y = 76.000
3y + 2y = 76.000
5y = 76.000
y = 76.000:5
y = 15.200

x = 3y
x = 3 dikali 15.200
x = 45.600
