both type of glass. He uses 216kg more slica to make one type of glass than other type. Find the quantity of slica used in each type.

let x and y be the two kinds of silica
:
x+y=1800........eq 1
x=y+216.........eq 2
:
take x's value from eq 2 and plug it into eq 1
:
y+216+y=1800
:
2y=1584
:
y=792
:
so x=792+216=1008
:
x=1008 and y=792
