HELPING MORTHER AT HOME

Every child should love his mother. A girl or boy learns’ many good things from mother. Mother teachers us to be obedient, helpful and friendly to others.

Ever since my young days I have always helped my mother in the kitchen. I get up early in the morning and help my mother prepare breakfast. Then I clean the kitchen and sweep the floor. I also help mother wash the post and pans.

On Sunday I follow my mother to the market and help her to carry vegetables and fish back home. Some times my mother asks me to cut vegetables. I readily do I wash vegetables. I like to give small help whenever I am free from school work.

One day when my mother was sick, I cooked dishes for lunch. My mother is always happy and tells me that I should be good to everyone.

Every mother will be happy if her children help her at home.

x/4=y/3;

y/6=z/11 => y/3=2z/11 => y=6z/11

và x/4=y/3=2z/11 => x=8z/11

x.y.z=8z/11.6z/11.z=-528 => z³=-(528.11.11)/(8.6)=-1331 = -11³  => z=-11;
