4x+7\times 3\pi =-56
Multiply both sides of the equation by 28, the least common multiple of 7,4.
4x+21\pi =-56
Multiply 7 and 3 to get 21.
4x=-56-21\pi
Subtract 21\pi from both sides.
4x=-21\pi -56
The equation is in standard form.
\frac{4x}{4}=\frac{-21\pi -56}{4}
Divide both sides by 4.
x=\frac{-21\pi -56}{4}
Dividing by 4 undoes the multiplication by 4.
x=-\frac{21\pi }{4}-14
Divide -56-21\pi by 4.
