21x+16y=385
Swap sides so that all variable terms are on the left hand side.
21x=385-16y
Subtract 16y from both sides.
\frac{21x}{21}=\frac{385-16y}{21}
Divide both sides by 21.
x=\frac{385-16y}{21}
Dividing by 21 undoes the multiplication by 21.
x=-\frac{16y}{21}+\frac{55}{3}
Divide 385-16y by 21.
21x+16y=385
Swap sides so that all variable terms are on the left hand side.
16y=385-21x
Subtract 21x from both sides.
\frac{16y}{16}=\frac{385-21x}{16}
Divide both sides by 16.
y=\frac{385-21x}{16}
Dividing by 16 undoes the multiplication by 16.
