-2x-6y=7+y
Use the distributive property to multiply -2 by x+3y.
-2x=7+y+6y
Add 6y to both sides.
-2x=7+7y
Combine y and 6y to get 7y.
-2x=7y+7
The equation is in standard form.
\frac{-2x}{-2}=\frac{7y+7}{-2}
Divide both sides by -2.
x=\frac{7y+7}{-2}
Dividing by -2 undoes the multiplication by -2.
x=\frac{-7y-7}{2}
Divide 7+7y by -2.
-2x-6y=7+y
Use the distributive property to multiply -2 by x+3y.
-2x-6y-y=7
Subtract y from both sides.
-2x-7y=7
Combine -6y and -y to get -7y.
-7y=7+2x
Add 2x to both sides.
-7y=2x+7
The equation is in standard form.
\frac{-7y}{-7}=\frac{2x+7}{-7}
Divide both sides by -7.
y=\frac{2x+7}{-7}
Dividing by -7 undoes the multiplication by -7.
y=-\frac{2x}{7}-1
Divide 7+2x by -7.
