7x+216y=1
Multiply 36 and 6 to get 216.
7x=1-216y
Subtract 216y from both sides.
\frac{7x}{7}=\frac{1-216y}{7}
Divide both sides by 7.
x=\frac{1-216y}{7}
Dividing by 7 undoes the multiplication by 7.
7x+216y=1
Multiply 36 and 6 to get 216.
216y=1-7x
Subtract 7x from both sides.
\frac{216y}{216}=\frac{1-7x}{216}
Divide both sides by 216.
y=\frac{1-7x}{216}
Dividing by 216 undoes the multiplication by 216.
