Just itself 5x
Three.

It is: 2x and 5x are like terms Addition: 2x+5x = 7x Multiplication: 2x*5x = 10x2

-4
No.
5x - 3 + x - 9 = 5x Bring like terms together of the left side: 5x + x - 3 - 9 = 5x Combine like terms: 6x - 12 = 5x Add 12 to both sides: 6x = 5x + 12 Subtract 5x from both sides: x = 12
They appear to be terms of an algebraic expression.
In an algebraic expression, terms are the elements separated by the plus or minus signs. On simplifying further we get: 8 - 5x and it has two terms: 8 & -5x. But, without simplifying we have four terms which are 3x, 8, -2x & -6x.
Two algebraic terms
To simplify the expression (3x + 2y + 5x - 6y), combine like terms. First, combine the (x) terms: (3x + 5x = 8x). Then, combine the (y) terms: (2y - 6y = -4y). Thus, the simplified expression is (8x - 4y).
