Rational expressions are divided into integral and fractional expressions. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. So,9x = 87 – 15⇒ 9x = 72, Dividing both sides by the coefficient of x, we get⇒ x = 72/9= 8Hence, x = 8, Question 3: Calculate the value of y in the following equation:7y – 31 = -10, Solution: First of all we separate constants from variables. Copyright © 2020 Entrancei. If an algebraic expression contains the root of the variable or the fractional power with a variable base then the expression is called irrational expression. Often in mathematics, we come across symbols or letters such as x, y, z, etc. So, 7y = -10 + 31⇒ 7y = 21, Dividing both sides by the coefficient of y, we get:⇒ y = 21/7= 3Hence, y = 3. Binomial Expression: An expression with two terms is known as a binomial. The constant that multiplies the variable (s) in a term is called the coefficient. Examples of binomial include 5xy + 8, xyz + x 3, etc. A collection of algebraic terms connected by mathematical symbols is called an algebraic expression, and an algebraic expression whose parts are not separated by + or − signs is called a term. So, 6x = 15 – 3⇒ 6x = 12, Dividing both sides by the coefficient of x, we get⇒ x = 12/6= 2Hence, x = 2, Question 2: Calculate the value of x in the following equation:9x + 15 = 87, Solution: First of all we separate constants from variables. With the introduction of Algebra in Class 6, it becomes difficult for students to understand the various concepts.
