x+2y=28x-7p
Multiply both sides of the equation by 7.
28x-7p=x+2y
Swap sides so that all variable terms are on the left hand side.
-7p=x+2y-28x
Subtract 28x from both sides.
-7p=-27x+2y
Combine x and -28x to get -27x.
-7p=2y-27x
The equation is in standard form.
\frac{-7p}{-7}=\frac{2y-27x}{-7}
Divide both sides by -7.
p=\frac{2y-27x}{-7}
Dividing by -7 undoes the multiplication by -7.
p=\frac{27x-2y}{7}
Divide -27x+2y by -7.
x+2y=28x-7p
Multiply both sides of the equation by 7.
x+2y-28x=-7p
Subtract 28x from both sides.
-27x+2y=-7p
Combine x and -28x to get -27x.
-27x=-7p-2y
Subtract 2y from both sides.
-27x=-2y-7p
The equation is in standard form.
\frac{-27x}{-27}=\frac{-2y-7p}{-27}
Divide both sides by -27.
x=\frac{-2y-7p}{-27}
Dividing by -27 undoes the multiplication by -27.
x=\frac{2y+7p}{27}
Divide -7p-2y by -27.
