Question

16+2b-7b subtracting like terms

Answer 1

Like terms are terms that have the same variables and powers/exponents.

The only like terms are 2b and -7b because they have the same variable "b" and the same power/exponent of 1, so you can combine them.

16 + 2b - 7b

16 - 5b

Answer 2

It equals 16+5b
2b-7b= 5b
