Answer:

given the expression  4x - 2y + z + 5 we see three terms of the expression:  4x, -2y, +z , 5.

Terms are made of two things, a coefficient and a variable.

coefficient       variable

     4                 x

    -2                 y

   +1                 z

   +5                 no variable exists in this term so it is a special term called a constant.

Coefficients can be +/-, fractions, decimals, whole numbers, etc.

In equations the coefficient is often shown as a letter such as

ax + by + 3.

This means (a times x) plus (b times y) plus 3

fractional coefficients looks like this example:   x/4  + y/2  - z/3

the coefficient for x is 1/4, the coefficient for y is 1/2 and the coefficient for z is -1/3Step-by-step explanation:
