## NCERT Solutions Chapter 9 Algebraic Expressions and Identities

In earlier classes, we have already become familiar with what algebraic expressions
(or simply expressions) are. Examples of expressions are:
x + 3, 2y – 5, 3x2, 4xy + 7 etc.
You can form many more expressions.As you know expressions are formed from variables and constants. The expression 2y – 5 is formed from the variable yand constants 2 and 5. The expression 4xy + 7 is formed from variables x and y and constants 4 and 7. We know that, the value of y in the expression, 2y – 5, may be anything. It can be The value of an expression changes with the value chosen for the variables it contains. Thus as y takes on different values, the value of 2y – 5 goes on changing. When y = 2, 2y – 5 = 2(2) – 5 = –1; when y = 0, 2y – 5 = 2 × 0 –5 = –5, etc. Find the value of the expression 2y – 5 for the other given values of y
