Word equations are equations in which mathematical operations are applied to words instead of numbers. Word equations are commonly used in chemistry and are used to show common chemical reactions. Word equations are written with the name of the substance instead of the chemical abbreviation.
Know MoreA basic word equation would be hydrogen gas + oxygen gas = steam. If the abbreviations and amounts are used in the equation, it is called a symbolic equation. In mathematics, a word equation could be used as an intermediate step in a word problem. One example could be boys + girls = total number of people.
Learn more about AlgebraA system of equations is a group of multiple equations solved simultaneously to reach the same or multiple solutions. Many systems of equations can be graphed on a coordinate plane for easy visualization and solving. However, not all systems have solutions, and some have many solutions.
Full Answer >Linear equations may be solved by isolating the variable or variables. Solving linear equations involves undoing whatever operations have been done to the variable and putting the variable alone on one side of the equal sign.
Full Answer >To solve an equation in one variable graphically, first manipulate the equation to put it in the form f(x) = 0, where x represents the variable present in the equation. Then use mathematical software, a graphing calculator or graph paper to plot the line y = f(x). The solution to f(x) = 0 is the point or points at which the line crosses the x-axis.
Full Answer >To solve rational equations, use the common denominator to resolve all the fractions. Removing the denominators makes it much easier to deal with the remaining terms, converting the problem into a simpler equation.
