Question

5z+3-3z in equivalent expression

Answer 1

2z +3

Explanation:

This question simply involves understanding what like terms are, and how to combine them.

Here, 5z and -3z are like terms, so we combine them by going 5z-3z = 2z

(i.e. we minus the coefficients, but the z stays unchanged).

Next, the number term of 3 in the middle cannot be combined with any other term, so it just stays in the expression.
