Question

Which of the follwoing is true for the equation: 6x - 7 = 0?

• A. 6 - coefficient, x - variable, 7 - constant
• B. x - coefficient, 6 - variable, 7 - constant
• C. x - coefficient, 7 - variable, 6 - constant
• D. 7 - coefficient, x - variable, 6 - constant

Answer 1

The correct option is A 6 - coefficient, x - variable, 7 - constant



$\Rightarrow$Variable - A variable is a letter whose value is unknown; and it always represents a number, but it carries varying values when written in an expression.
Here in this expression, the value of x is unknown.
So, x is a variable.

$\Rightarrow$Coefficient - Coefficient is a number that is being multiplied by the variable.
6 is multiplied with x. So, 6 is the coefficient of x.

$\Rightarrow$Constant number -A constant is a value or number that never changes in expression; it’s constantly the same.
So, 7 is a constant number
