Writing a solution set

Elementary Row Operations Elementary Row Operations are operations that can be performed on a matrix that will produce a row-equivalent matrix. If the matrix is an augmented matrix, constructed from a system of linear equations, then the row-equivalent matrix will have the same solution set as the original matrix.

Consumption of processed and convenience foods and our dependence on the car have led to an increase in obesity and reduction in the fitness level of the adult population. In some countries, especially industrialized ones, the number of obese people can amount to one third of the population.

This is significant as obesity and poor fitness lead to a decrease in life expectancy, and it is therefore important for individuals and governments to work together to tackle this issue and improve their citizens' diet and fitness. Obesity and poor fitness decrease life expectancy.

Overweight people are more likely to have serious illnesses such as diabetes and heart disease, which can result in premature death. It is well known that regular exercise can reduce the risk of heart disease and stroke, which means that those with poor fitness levels are at an increased risk of suffering from those problems.

Changes by individuals to their diet and their physical activity can increase life expectancy. There is a reliance today on the consumption of processed foods, which have a high fat and sugar content.

By preparing their own foods, and consuming more fruit and vegetables, people could ensure that their diets are healthier and more balanced, which could lead to a reduction in obesity levels.

The Best Way to Write a Problem Statement (with Example)

In order to improve fitness levels, people could choose to walk or cycle to work or to the shops rather than taking the car. They could also choose to walk up stairs instead of taking the lift. These simple changes could lead to a significant improvement in fitness levels.

Governments could also implement initiatives to improve their citizens' eating and exercise habits. This could be done through education, for example by adding classes to the curriculum about healthy diet and lifestyles. Governments could also do more to encourage their citizens to walk or cycle instead of taking the car, for instance by building more cycle lanes or increasing vehicle taxes.

Of the solutions suggested, those made by individuals themselves are likely to have more impact, though it is clear that a concerted effort with the government is essential for success. With obesity levels in industrialized and industrializing countries continuing to rise, it is essential that we take action now to deal with this problem.The solution set of the single equation = is the set {0}.

2. For any non-zero polynomial f {\displaystyle f} over the complex numbers in one variable, the solution set is made up of finitely many points. A linear system with a unique solution has a solution set with one element.

A linear system with no solution has a solution set that is empty. In these cases the solution set is easy to describe. Solution sets are a challenge to describe only when they contain many elements.
