One pair, 10z and -4z, since like terms are only terms that contain the same variable(s) with the same exponent.
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.
None of them.
