By definition a term is the basic unit of algebra which must contain 3 parts - a sign, a coefficient and a variable (e.g., 2n [+ sign implied, coefficient '2' and variable 'n'] and -7d). In the expression 2n-4-7d then, there are 2 terms.
They are terms of an algebraic expression which can be simplified to: 2s+2d
It would be: 3(7-d) as an algebraic expression
It is: d/7
d + 5
The variable is d, in the algebraic expression 7d+2
Bisect :D Glad to be of help!

You have to switch the sign of all terms within the parentheses. For example, -(a - b + c - d) becomes -a + b - c + d
It would be: 3(7-d) as an algebraic expression
It is: d/7
The algebraic expression is: d-100
d + 5
The variable is d, in the algebraic expression 7d+2
d - 6 (or x = d - 6).
It is: d
An algebraic expression. 4 = the constant and coefficient term. d = the variable term.
D - 38 = x
