Byju's linear equations class 8
WebDefinition: A linear equation is defined as an algebraic equation in which each term has an exponent of 1 and when graphed, the result is always a straight line. In other words, a linear equation is an equation with a maximum degree of 1. Here, we’ll go through a variety of linear equations problems with solutions, based on various concepts. WebAccess Answers to NCERT Class 8 Maths Chapter 2 – Linear Equations in One Variable Exercise 2.5 Page Number 33 Solve the following linear equations. 1. x/2 – 1/5 = x/3 + ¼ Solution: x/2 – 1/5 = x/3 + ¼ ⇒ x/2 – x/3 = ¼+ 1/5 ⇒ (3x – 2x)/6 = (5 + 4)/20 ⇒ 3x – 2x = 9/20 × 6 ⇒ x = 54/20 ⇒ x = 27/10 2. n/2 – 3n/4 + 5n/6 = 21 Solution:
