3/5 kg of clay are divided into 1/5 a kilogram, so how many times is 1/5 in 3/5?
equation is
Subsitution
4x+y=210
minus 4x both sides
y=210-4x
sub 210-4x for y in other equation
3x+2(210-4x)=195
3x+420-8x=195
-5x+420=195
minus 420 both sides
-5x=-225
divide both sides by -5
x=45
sub back
y=210-4x
y=210-4(45)
y=210-180
y=30
x=45
y=30
(x,y)
(45,30)
