NCERT Solutions for Class 7 Maths Chapter 4: Simple Equations

iacst-2022

An equation is a mathematical statement on a variable where two expressions on either side of the equality sign should have equal values. The simple equation represents the relationships of two expressions on either side of the sign. It has one variable. The expressions on two sides are called LHS(left-hand side) and RHS(right-hand side). A variable takes on a different numeric value, and a constant has a fixed value. In Ex 4.1, students will learn about what equation means. There is an equality sign in any equation that shows the value of the expression to the left sign of the equation is equal to the equation's right side. In Ex 4.2, you will learn how to calculate or solve an equation.

In an equation, both the sides should be equal. An equation remains unchanged when Lhs and Rhs are interchanged, when the same number is added to both the sides when the same number is subtracted from both the sides, the same number is multiplied from both sides the Rhs, and Lhs is divided by the same number. In Ex 4.3, students will get to know about moving a number from one side to another instead of adding and subtracting it from both sides of the equation. In Ex 4.4, you will learn how to use Simple equations in the practical Questions. Here you will be given a practical question according to which you have to form equations and solve it. Some Important topic for this chapter are:

  • What is an Equation
  • Solving an equation
  • More Equation
  • From solution to the equation
  • Application of simple equations to the practical equation.
