Question

mention the constant and the variable in the following term : 9x/y

Answer 1

Answer:

Find constant and variables  in the given expression.

(i) 3x = 9

(ii) x – y = -10

Solution:

(i) In 3x = 9,

x is the variable and 9 is the constant.

If we further simplify the equation,

3x = 9

x = 9/3 = 3

then x is the variable and 3 is the constant.

(ii) x-y = -10

Here, x and y are the variables and -10 is the constant value.
