Before multiplying, change any mixed numbers to improper fractions. Remember to always check your solution.

.

For using the factorisation method, the quadratic equation should be in descending order. It is already given in descending order. Similarly, all the terms in the left-hand side of the equation and there is no term in the right hand side of the equation. So, we can start the process for factoring the quadratic equation to solve it. The trinomial in the quadratic expression is expanded as a quadrinomial.

Apply the orderly steps established in this section to systematically solve equations. Dividing by 5 does not help find the solution however. Toggle navigation GetEasySolution. What number should we divide by to find the solution? To check we substitute 6 for x in the equation to see if we obtain a true statement. The multiplication rule allows us to avoid these operations when solving an equation involving fractions by finding an equivalent equation that contains only whole numbers. Remember that when we multiply a whole number by a fraction, we use the rule. Multiplying each side of the equation by 15, we obtain Why do we multiply both sides by 15? If the perimeter of a rectangle is 54 cm and the length is 15 cm, what is the width? Example 9 What number x has the same ratio to 3 as 6 has to 9?

Check how easy it is, and learn it for the future. We now look at a solution that requires the use of both the subtraction rule and the division rule. A conditional equation is true for only certain values of the literal numbers in it. Our answer is Help Tutorial. Techniques for solving equations will involve processes for changing an equation to an equivalent equation. If we choose to first add 2x to both sides, we obtain We now add 2 to both sides. First Eliminate fractions, if any, by multiplying each term of the equation by the least common multiple of all denominators of fractions in the equation. We now wish to introduce an idea that is a step toward an orderly process for solving equations. Determine if certain equations are equivalent.
