The solution of equations is the central theme of algebra. In this chapter we will study some techniques for solving equations having one variable. To accomplish this we will use the skills learned while manipulating the numbers and symbols of algebra as well as the operations on whole numbers, decimals, and fractions that you learned in arithmetics. Upon completing this section you should be able to: Classify an equation as conditional or an identity, x 2 x 3 answer.

.

If each term of an equation is divided by the same nonzero number, the resulting equation is equivalent to the original equation. Third Add or subtract the necessary quantities to obtain the unknown quantity on one side x 2 x 3 answer the numbers of arithmetic on the other side. Upon completing this section you should be able to: Use the division rule to solve equations.

.

If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0. Set x - 3 equal to 0 and solve for x. A bag of 11 marbles contains 7 marbles with red on them, 3 with blue on them, 5 with green on them, and 4 with red and green on them. What is the probability that a randomly chosen marble has either green or red on it? Note that these events are not mutually exclusive. Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth. If it took a car 25 feet to come to a complete stop after stepping on the brakes, estimate the speed of the car.

First subtract 6 from both sides. If we choose to first add 2x to both sides, we obtain We now add 2 to both sides. Feel free to try them now. Apply the orderly steps established in this section to systematically solve equations. Why do we multiply both sides by 15? Two equations are equivalent if they have the same solution set. To check an answer to a system of equations containing x and y, enter the two equations separated by a semicolon, followed by the sign and an ordered pair containing your x-value and y-value. A solution or root of an equation is the value of the variable that makes the equation a true statement. Example 6. We now have an equivalent equation that contains only whole numbers. If the same quantity is added to both sides of an equation, the resulting equation is equivalent to the original equation. Notice how new ideas in algebra build on previous knowledge. Multiplying each side of the equation by 15, we obtain Why do we multiply both sides by 15? The ratio of a number x to a number y can be written as x:y or.

.

In the example we need to multiply by a number that is divided by 3. MathPapa Toggle navigation. In the Calculator's text box, you can enter a math problem that you want to calculate. Many students think that when they have found the solution to an equation, the problem is finished. We now look at a solution that requires the use of both the subtraction rule and the division rule. Fourth Divide by the coefficient of the unknown quantity. To have a true statement we need a value for x that, when added to 3, will yield 7.

If the same quantity is subtracted from both sides of an equation, the resulting equation will be equivalent to the original equation. Welcome to Quickmath Solvers!
