286x+y=15
Anything divided by one gives itself.
286x=15-y
Subtract y from both sides.
\frac{286x}{286}=\frac{15-y}{286}
Divide both sides by 286.
x=\frac{15-y}{286}
Dividing by 286 undoes the multiplication by 286.
286x+y=15
Anything divided by one gives itself.
y=15-286x
Subtract 286x from both sides.
