For this case we must find the solution of the following equation:

Applying distributive property on the right side of the equation we have:

Subtracting 7x from both sides of the equation:

Subtracting 20 from both sides of the equation:

Different signs are subtracted and the major sign is placed.

Dividing between -2 on both sides of the equation:

Thus, the solution of the equation is
Answer:
