8*(x+2)=32+4*(x+2)                                   15*(a-4)=42+8*(a-4)                         
8x+8*2=32+4x+4*2                                    (y+1)*18=36+12*(y+1)
8x+16=32+4x+8                                          (k+5)*7-54=(k+5)*4
8x+16=40+4x                                              17*(c-2)-36=19+(c-2)*12
8x+16-4x=40+4x-4x
4x+16=40

My favorite month is July. I like it very much, and every year I look for him with great pleasure. I enjoy every moment of this beautiful month. July is the hottest month of the summer. In July, the weather is usually wonderful,the sky is clear and cloudless. Sometimes the sky is covered by a huge clouds. Sometimes, the storm of thunder and lightning. The days are long and the nights are short and dark. Most people prefer to take a vacation in July. It is time for the holidays. People going to the beach to sunbathe, swim and relax. People trying to escape from the city noise and spend more time outdoors. To enjoy your time at the beach or somewhere outside the city. They collect mushrooms and berries in the forest, swim in rivers and lakes, fish and swim to the boat. July brings fruits and vegetables.
