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.

.

That is, in the expression 5x the coefficient is 5. In the example we need to multiply by a number that is divided by 3.

.

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. Triangle J K L is shown. Round to the nearest whole degree. Solve the recurrence relations together with the initial conditions given.

To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the sign and an ordered pair containing your x-value and y-value. Here our goal of obtaining x alone on one side would suggest we eliminate the 2x on the right, so we add 2x to both sides of the equation. A ratio is the quotient of two numbers. Note that there are four terms in this equation. What number should we divide by to find the solution? Here again, we needed to use both the addition rule and the division rule to solve the equation. An identity is true for all values of the literal and arithmetic numbers in it. Fifth Check your answer. Note that in this example we used three rules to find the solution. Here our task is the same but a little more complex. We now wish to introduce an idea that is a step toward an orderly process for solving equations. The literal numbers in an equation are sometimes referred to as variables.

.

Determine if certain equations are equivalent. Polynomials Algebra Calculator can simplify polynomials, but it only supports polynomials containing the variable x. To prepare to use the division rule for solving equations we must make note of the following process:. Example 6. The answer to the first question is found by using the substitution principle. Step 2 Combine like terms on each side of the equation. Notice how new ideas in algebra build on previous knowledge. This means "1 person is to 3 cubic meters as x people are to cubic meters. To solve an equation follow these steps: Step 1 Eliminate fractions by multiplying each term by the least common multiple of all denominators in the equation. Example 6 Solution Here our task is the same but a little more complex. Evaluating Expressions Algebra Calculator can evaluate expressions that contain the variable x. Could we first add 2 to both sides? If the perimeter of a rectangle is 54 cm and the length is 15 cm, what is the width? Example 4 Solve for x: 0. Here our goal of obtaining x alone on one side would suggest we eliminate the 2x on the right, so we add 2x to both sides of the equation.
