Simple Equations Class 7 Notes: Chapter 4
An equation, also known as the algebraic equation, is a condition on a variable such that two expressions in the variable have equal value. A variable’s value is not fixed, it takes the value of different numerical values. An equation has an equality sign. The equality sign proves that the value of the expression to the left-hand side or LHS is equal to the value of the expression to the right-hand side or RHS. An equation remains the same, even when the L.H.S and R.H.S of the equation are interchanged. Please refer Simple Equations Class 7 Notes for more revision notes.
