#### About NCERT Solutions for Class 7 Maths Chapter 4

In 7 Maths Chapter 4 Simple Equations, we will study about the formation of linear equations in one variable (A variable takes on different numerical values; its value is not fixed. Variables are denoted usually by letters of the alphabets, such as x, y, z, l, m, n, p, etc.). In an equation there is always an equality sign. The equality sign shows that the value of expression to the left hand side or LHS is equal to the value of the expression to the right hand side or RHS. Remember the following things for an equation:

1. If we subtract the same number from both sides of an equality, it still holds.

2. If we multiply or divide both sides of the equality by the same non-zero number, it still holds.

3. Transposing a number (changing the side of the number) is the same as adding or subtracting the number from both sides.

Note: If we fail to do the same mathematical operation on both sides of an equality, the equality does not hold.

To solve the practical problems based on equations, first convert the situation into equation and then apply the mathematical operation on it.

### Important Questions on Class 7 Maths Chapter 4

##### Check whether the value given in the brackets is a solution to the given equation or not: n + 5 = 19 [ n = 1].

n + 5 = 19 Putting n = 1 in L.H.S., 1 + 5 = 6 L.H.S. R.H.S., n = 1 is not the solution of given equation.

##### Write equations for the following statement: The sum of numbers x and 4 is 9.

x + 4 = 9

##### Write the following equations in statement form: 4 p – 2 = 18.

If you take away 2 from 4 times p you get 18.
