Question

we can describe 3x-2 as an expression.
how can we describe the parts of the expression

Answer 1

Answer:

In each of the terms 3x 2 and 7x, x is a variable, and in both terms, we are multiplying a number by the variable. In the first term, 3x 2, 3 is being multiplied by the variable, so 3 is a coefficient. In the second term, 7x, 7 is being multiplied by the variable, so 7 is a coefficient.

Answer 2

The different parts of the equation $3x-2$ can be described as follows:

• In the above equation, $x$ is known as a variable. A Variable is a symbol used to denote an unknown numerical value in an equation.
• $3$ is the co-efficient to the variable. A co-efficient is the number that is multiplied by the unknown numerical value in a particular equation.
• Variables with no co-efficient have co-efficient 1.
• $2$ is the constant in the equation. A constant is such a number whose value does not change. In the given equation, no matter what is the value of $3x$, 2 will always get subtracted.
