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 AlgebraTo 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 >Solve quadratic equations by graphing, using square roots, factoring, completing the square or using the quadratic formula. Determine the most appropriate method by considering the particular situation.
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 >A 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.
