Apparent magnitude isn’t the actual brightness, it’s what the brightness appears to be from earth, absolute brightness is the actual brightness an example is our sun it appears bright on earth but in space it is so much more brighter
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)
